Spinel Ferrite
This book explores the synthesis, characterization, and analysis of the physical properties of spinel ferrites, with a focus on doped lithium ferrites. The research investigates how chromium (Cr) and manganese (Mn) doping affects the structural, magnetic, and electrical properties of these materials, which are of interest due to their potential applications in electronic, magnetic, and high-frequency devices.The work begins by highlighting the significance of ferrites in modern technology, particularly their unique magnetic properties and versatility. Spinel ferrites, in particular, exhibit a wide range of tunable properties that make them suitable for various applications. The synthesis of Cr- and Mn-doped lithium ferrites is achieved through advanced methods, and the resulting materials are characterized using a suite of techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometry (VSM).Key findings of the study demonstrate how doping with chromium and manganese alters the structural and magnetic behaviour of the lithium ferrites, leading to materials with tailored properties for specific technological uses.

Quantum Gravity Phenomenology II
Quantum gravity is at the frontier of research in physics. The four known interactions - gravitational, electromagnetic, strong and weak nuclear forces - have successfully described all known phenomena, with the exception of the dark sector. Of the four, the quantum of gravitational interaction is yet to be discovered, due to the weakness of the interaction at small scales. However, gravitational interaction is very strong for astrophysical objects, and bizarre phenomena have been tested experimentally. Using general relativity, gravity is shown as the theory of space-time, and theoretical predictions of black holes, and gravitational lensing, have all been observed in astrophysics. Gravitational waves, recently discovered, brings forth new hope for observational gravitational physics in the realm of the infinitesimal, to the point that the physics of quantum gravity may be within reach. The two volumes of the Universe Special Issue on quantum gravity phenomenology are therefore very timely, with papers describing the search for quantum signatures of gravity in observational physics. Due to the difficulty or impossibility of direct experiments, One of the avenues explored is analog models of gravity. Curved graphene was used to simulate the geometry of the outside of a black hole, and supersonic matter waves could simulate horizon behavior in fluids. Volume I of the Special Issue focuses on these "simulated quantum gravity experiments" or analog models with papers by pioneers in the field. Volume II describes quantum effects in astrophysical and cosmological phenomena which provide predictions for future experiments.

Vectors and Kinematics
This book is designed as a basic and fundamental guide to Physics knowledge. This covers the following topics: vectors, concepts of physical variables, kinematics, motion with constant velocity, motion with constant acceleration, vertical launch upward and free fall, parabolic motion, circular motion and centripetal acceleration, varied circular motion and angular acceleration. This includes the deduction of many formulas to clarify the concepts and fill all the needs of the students to reach the foundations of Physics. Finally, another objective of the book is to achieve the interest and motivation of the students for the real nature of Physics.
Echoes from the Pre-Dawn Unseen Cosmos
The Book explains the connection between physics and the endeavor to attain a general philosophy of the world: and it may well be asked wherein this interconnectivity lies. Physics, it may be argued, is solely concerned with the objects and events of inanimate nature, while a general philosophy, if it is to be at all satisfactory, must embrace the whole of physical and intellectual life and must deal with questions of the soul, including the highest problems of ethics. At first this objection may seem convincing. Yet it will not bear closer investigation. In the first place inanimate nature is, after all, part of the world so that any philosophy of the world claiming to be truly comprehensive must take notice of the laws of inanimate nature; and in the long run such a philosophy becomes untenable if it conflicts with inanimate nature. It will be the chief purpose of the current book to demonstrate the influence in greater detail with regard to Physics.
Nano-structured metal oxide thick films and electrical conductivity
Currently there is a flourishing world-wide interest in 'nano science' research which attempts to make and organize objects on the nanometer length scale. As a result of increasing ability to artificially assemble and condensed matter at the nanometer scale, where properties are often changed dramatically and processing high performance material for wide verity of applications is becoming possible. Continued efforts in this field may lead to the development of novel materials with technologically important properties.The properties of nano crystalline materials are very often superior to those of conventional poly crystalline materials. They exhibit increased strength / hardness, enhanced diffusivity, improved ductility / toughness, reduce density, reduced elastic modulus, higher / lower electrical resistivity depending on the material, increased specific heat, higher thermal expansion coefficient, lower thermal conductivity, superior soft magnetic properties, etc., in comparison to conventional materials. New concepts of nano composites are also being investigated with special emphasis in ceramic composites to increase their strength and toughness.
Radiative Processes in Astrophysics
Radiative Processes in Astrophysics This clear, straightforward, and fundamental introduction is designed to present-from a physicist's point of view-radiation processes and their applications to astrophysical phenomena and space science. It covers such topics as radiative transfer theory, relativistic covariance and kinematics, bremsstrahlung radiation, synchrotron radiation, Compton scattering, some plasma effects, and radiative transitions in atoms. Discussion begins with first principles, physically motivating and deriving all results rather than merely presenting finished formulae. However, a reasonably good physics background (introductory quantum mechanics, intermediate electromagnetic theory, special relativity, and some statistical mechanics) is required. Much of this prerequisite material is provided by brief reviews, making the book a self-contained reference for workers in the field as well as the ideal text for senior or first-year graduate students of astronomy, astrophysics, and related physics courses. Radiative Processes in Astrophysics also contains about 75 problems, with solutions, illustrating applications of the material and methods for calculating results. This important and integral section emphasizes physical intuition by presenting important results that are used throughout the main text; it is here that most of the practical astrophysical applications become apparent.

The Big Questions of Science
Of all the species that live on this planet, as far as we know, man is the only one capable of awareness; observing the sky, understanding its beauty, and asking questions about the meaning of life and that of death, on the beginning and the end, both about the Universe and man himself. The questions range in all directions: why is there something instead of nothing? Who is the architect of reality, and why does it appear to us as it does, rather than in some other way? What's the point of all this? Where does life originate, and what are the origins of the Universe that encompasses it?This book aims to introduce and address the questions that are often asked and answer with the knowledge that science provides us. Where does all the matter we are made of come from and what constitutes the Universe? Is it true that there is matter and energy whose existence can be intuited only indirectly, as the existence of the wind is deduced from leaves' motion? Einstein was right in his revolutionary description of reality, on nature of space and time, inextricable units in their apparent dichotomy. Does each observer truly observe a 'different' time from another observer? Can we move back and forth in the time? How space and time are modified by astronomical objects such as black holes, and what is the nature of the latter? Will time and the Universe end and how did they originate? The Universe is incredibly vast, housing hundreds of billions of galaxies within the observable Universe alone. Beyond what we can observe, there may exist an unimaginably vast expanse that extends infinitely and beyond our imagination. Our Universe, enormous as it may be, is not the only one. That's all predicted by certain cosmological and physical theories. Is life unique to Earth, or does the Universe harbor other forms of life that remain undiscovered to us? Finally, we are confronted with the most intriguing and elusive question of all: was all of this deliberately planned by some higher power, or is it merely a result of natural processes? Each of these questions touch on a fundamental aspect of our perception of the Universe and our quest to comprehend humanity's place in the cosmos.

Optical studies and judd ofelt analysis of RE doped Sr2SiO4 NPs
Spectroscopy is the study of interaction of electromagnetic radiation with matter. Optical spectroscopy is widely used in the characterization of nanostructured materials and can broadly be classified into two types: absorption and emission spectroscopy and the other is vibrational spectroscopy. Among these absorption and emission spectroscopy is used to determine the electronic structure of atoms, ions, molecules etc. The study of behavior of the electrons in the atoms or molecules exciting to a particular higher state from their ground state by the absorption of the photon of suitable energy is absorption spectroscopy. The electrons excited to the higher states are short lived and will de-excite to its initial state by different processes. Thus, the study of behavior of such electrons relaxing to the ground state is termed as emission spectroscopy.
Characterization and production of an electrical device based on graphene
The general objective of the work we are developing consists of the process of fabricating devices in two-dimensional materials, including lithography, metal deposition for electrical contact patterns, morphological characterization and electrical measurements. The sample was produced using a method called Mechanical Cleaving. This method basically consists of manually separating the stacked layers of a graphite crystal repeatedly by sticking and peeling the crystal to a piece of tape. This is then attached to the silicon dioxide substrate and pressed manually so that the flakes adhere to the substrate. The number of layers in the sample was determined by optical microscopy. The sample was also analyzed using Raman spectroscopy. To manufacture the contacts, a LaserWriter LW405 was used for optical lithography, followed by Cr/Au deposition and a lift-off process to finalize the device. Our work aims to understand the basic characteristics of electrical transport, the device fabrication process, electrical measurements and morphological characterization, as well as contributing to the first steps in the process.
Foundations of Quantization
The intensive path of development of science has led not only to the compilation of a large amount of poorly systematized knowledge about nature but also to the fact that under this "cultural layer" many magnificent ideas of the luminaries of the last century were found. This primarily concerns quantum theory, which has departed from the principles of quantization of Planck-Einstein and degenerated into a formal science, which not only does not need to be understood but also is forbidden to be understood. However, starting from the Planck-Einstein spatial resonances called quanta, we get a transparent physical picture and can correct a number of theories.The foundation of this book was laid by the popular science article "Uncombed Physics and the Particle of God" (http: //rusnor.org/pubs/articles/8058.htm). This is what the Higgs boson was pompously called when Higgs was awarded the Nobel Prize. This work was continued by the author in subsequent books in which the author deliberately (for self-control) tried to include only the material that had passed the examination in scientific journals. This book includes both the author's early scientific works, which identified problems in elementary basic models, and the author's latest, which gave ways to solve fundamental problems.

Material Point Mechanics
This is a classic mechanics course for students in the Math/Physics preparatory classes. However, thanks to the supplements in this course, the future teacher will also be able to find subjects to think about and go into in greater depth. This course covers the main aspects of Newtonian mechanics, such as the notion of force, Newton's laws, the energy point of view, angular momentum and the forces of inertia. It's a natural presentation that tries not to be too abstract, like that of torsors or analytical mechanics. More technical aspects may be covered in supplements.
Principles of Computational Modeling
The book deals with the contribution of theoretical calculations and predictions in the development of advanced high-performance thermoelectrics. The work has been increasingly significant and has successfully guided experiments to understand as well as achieve record-breaking results. In this review, recent developments in high-performance nanostructured bulk thermoelectric materials are discussed from the viewpoint of theoretical calculations. An effective emerging strategy for boosting thermoelectric performance involves minimizing electron scattering while maximizing heat-carrying phonon scattering on many length scales. We present several important strategies and key examples that highlight the contributions of first-principles-based calculations in revealing the intricate but tractable relationships for this synergistic optimization of thermoelectric performance.
Rules for Eternity
What are the fundamental laws of existence? Do they shape the universe before creation, or do they unfold as life evolves? Is intelligent life a cosmic inevitability or a fleeting accident? And most importantly-what are our true limits as conscious beings?In Rules for Eternity, John Hunter embarks on a thought-provoking exploration of the biggest scientific and philosophical questions of our time.

He studied Physics and Engineering at the University of Melbourne, learning from some of the country's top scientists. His lifelong fascination with how things work led him beyond astrophysics and mechanics into the realms of philosophy. After years of research, he felt compelled to contribute his own insights-resulting in Rules for Eternity, a thought-provoking exploration of the principles that shape our universe.
Seismic Wave Propagation Through Random Media
The solid Earth's medium is heterogeneous over a wide range of scales. Seismological observations, including envelope broadening with increasing distance from an earthquake source and the excitation of long-lasting coda waves, provide a means of investigating velocity inhomogeneities in the lithosphere. These phenomena have been studied primarily using radiative transfer theory with random medium modelling. This book presents the mathematical foundations of scalar- and vector-wave scattering in random media, using the Born or Eikonal approximation, which are useful for understanding random inhomogeneity spectra and the scattering characteristics of the solid Earth. A step-by-step Monte Carlo simulation procedure is presented for synthesizing the propagation of energy density for impulsive radiation from a source in random media. Simulation results are then verified by comparison with analytical solutions and finite-difference simulations. Presenting the latest seismological observations and analysis techniques, this is a useful reference for graduate students and researchers in geophysics and physics.
Fluid Mechanics
The classic textbook from Pijush Kundu, Fluid Mechanics, has been once again revised and updated by Dr. David Dowling and Dr. Jesse Capecelatro to better illustrate this important subject for modern students. With expanded topics and concepts presented more clearly in a revised didactic sequence, Fluid Mechanics, Seventh Edition guides students from the fundamentals to the analysis and application of fluid mechanics, including turbulence, gravity waves, compressible flow and such diverse applications as aerodynamics and geophysical fluid mechanics. Its broad and deep coverage, provided by 15 Chapters, 4 Appendices, 144 examples, and 568 exercises, continues to be ideal for both a first or second course in fluid mechanics at the graduate or advanced undergraduate level, and is well-suited to the needs of modern scientists, engineers, mathematicians, and others seeking fluid mechanics knowledge.
Engineering Energy Storage
Engineering Energy Storage, Second Edition, explains the engineering concepts of different energy technologies in a coherent manner, assessing underlying numerical material to evaluate energy, power, volume, weight, and cost of new and existing energy storage systems. Offering numerical examples and problems with solutions, this fundamental reference on engineering principles gives guidance on energy storage devices, setting up energy system plans for smart grids, engineering single technologies and comparing them, understanding the reasoning for losses in efficiency, and much more. This new edition advances the description of energy revolutions, with the premise that we are now in the most invasive and comprehensive energy revolution since the first industrial revolution. There is increased focus on the specifics of energy and power, as well as charging times for energy storage solutions compared to traditional means. The chapter on batteries is extensively expanded and now considers the carbon footprint of battery production and battery production processes. All technology costs are updated, and mineral limitations for the technologies are also discussed. More information regarding use scenarios for different energy storage solutions is included, and the exercises and worked problems are renewed and augmented, giving the reader a deeper understanding of the engineering aspects of energy storage. Designed for those in traditional fields of science as well as professional engineers in applied industries, this book is an ideal resource for undergraduate and postgraduate students, engineers, R&D, and industrial personnel working with energy storage systems or looking to extend their competencies into new areas.
Graphitization of Synthetic Diamonds with Laser
Here we provide a comprehensive overview of laser treatment for chemical vapor deposition (CVD) synthetic diamonds, followed by new data concerning another type of material-synthetic high-pressure high-temperature (HPHT) diamonds. The primary aim of this research is to investigate the graphitization processes occurring in HPHT synthetic single crystal diamonds. The study examined how impurities in samples affect its absorption properties and single/multipulse graphitization thresholds. Furthermore, an analysis of the surface composition using Raman spectroscopy revealed a diverse array of carbon structures that form in response to different levels of irradiation energy. This indicates that the interaction between the laser treatment and the material's inherent properties can lead to various structural outcomes. Through this research, we aim to enhance our understanding of the graphitization processes in HPHT synthetic diamonds and their potential applications in various fields.
Coronal Mass Ejections and Their Environmental Effects
The aim of this book is to provide up-to-date information about Coronal Mass Ejections (CMEs), which is one of the most puzzling and outstanding problems in solar physics. Every main sequence star is losing mass, caused by dynamic phenomena in its atmosphere that accelerate plasma or particles beyond the escape speed. Inspecting the Sun, our nearest star, we observe two forms of mass loss: the steady solar wind outflow and the sporadic ejection of large plasma structures, termed coronal mass ejections. In this book author Studied about CMEs; which is one of the main eruptive phenomena from Sun and try to summarized the properties of CMEs during solar cycle 23 and their geospace consequences.
Listening in the Field
The transformation of sound recording into a scientific technique in the study of birdsong, as biologists turned wildlife sounds into scientific objects. Scientific observation and representation tend to be seen as exclusively visual affairs. But scientists have often drawn on sensory experiences other than the visual. Since the end of the nineteenth century, biologists have used a variety of techniques to register wildlife sounds. In this book, Joeri Bruyninckx describes the evolution of sound recording into a scientific technique for studying the songs and calls of wild birds and asks, what it means to listen to animal voices as a scientist. The practice of recording birdsong took shape at the intersection of popular entertainment and field ornithology, turning recordings into objects of investigation and popular fascination. Shaped by the technologies and interests of amateur naturalism and music teaching, radio broadcasting and gramophone production, hobby electronics and communication engineering, birdsong recordings traveled back and forth between scientific and popular domains, to appear on gramophone recordings, radio broadcasts, and movie soundtracks. Bruyninckx follows four technologies--the musical score, the electric microphone, the portable magnetic tape recorder, and the sound spectrograph--through a cultural history of field recording and scientific listening. He chronicles a period when verbal descriptions, musical notations, and onomatopoeic syllables represented birdsong and shaped a community of listeners; later electric recordings struggled with notions of fidelity, realism, objectivity, and authenticity; scientists, early citizen scientists, and the recording industry negotiated recording exchange; and trained listeners complemented the visual authority of spectrographic laboratory analyses. This book reveals a scientific process fraught with conversions, between field and laboratory, sound and image, science and its various audiences.
Silicon Carbide
The continuous demand for electronic devices operating at increasing current and power levels has driven research into wide-bandgap (WBG) semiconductors in recent decades. In particular, the 4H hexagonal polytype of silicon carbide (4H-SiC) is the most promising for use in power electronic applications in the medium- to high-voltage range. However, to achieve the optimised performance of these 4H-SiC devices, a full understanding of the fundamental material properties, processing technology, and carrier transport mechanisms is required with wide margins for the progress of the related scientific and technological research into this material. On the one hand, an improvement in the existing power device performances in terms of efficiency and reliability is targeted; on the other hand, the 4H-SiC applications are desirably extendable toward new cutting-edge technologies, e.g., quantum technologies. This Special Issue collated 11 regular and 1 review papers. These papers can be summarized into three parts: the investigation of conventional 4H-SiC devices, the suggestion of new approaches for improved devices, and the use of SiC devices in emerging technology fields. Clearly, due to the broadness of 4H-SiC technology, the present collection cannot include all prominent issues. However, we are confident that fundamental properties and novel approaches have been discussed, hoping that this Special Issue will provide interesting inputs for 4H-SiC-based technology advancement.
Universe
This Special Issue aims to set itself at the cutting edge of the most recent advances in the intertwined ties of cosmology with other fields at all relevant scales from mutually fertilizing theoretical, phenomenological, and experimental perspectives. Topics include, but are not limited to, the following: cosmological models; inflationary cosmology; big bang; bounce cosmology; cosmic string/string theory; quantum cosmology; observational cosmology; ΛCDM cosmology; dark matter and dark energy; axion cosmology; cosmic acceleration; cosmological constants; cosmological perturbation theory; cosmic microwave background (CMB); Hubble's law/constants; machine learning and cosmology; and the large-scale structure of the universe. It is our pleasure that this Special Issue on various recent topics in modern cosmology and related fundamental physics is useful for future studies.
Zinc-Vanadate Glasses
Glasses' optical qualities are crucial for a wide range of commercial and scientific uses, including lasers, waveguides, optical fibers for optical communications, windows, glass containers, and camera lenses. Compared to crystals, glasses provide a number of advantages as solid laser host materials. It is simple to modify a number of physical parameters, such as temperature coefficients, to create a thermally stable cavity for laser applications. Glasses with low thermal conductivity have thickness requirements that must be met in order to employ high power lasers. Disorder in the glass's structure results in uniformly widened lines. In doing so, the magnified spontaneous emission losses are decreased and the threshold is raised. Q-switched applications make use of this characteristic. Using greater bandwidth, mode-locked operation can produce shorter pulses.
Introduction to analytical mechanics
The book covers coordinate systems, Newton's laws, projectiles and air resistance/drag, and charged particle motion. It can also cover momentum, angular momentum, energy and conservative forces. On the other hand, oscillations, Fourier analysis, calculus of variations, Lagrange's equations and central-force problems are the main topics can only be studied in Analytical Mechanics. Moreover, mechanics in non-inertial frames and rotational motion of rigid bodies (if there is time) are other topics that can be covered in this branch of mechanics. The kinetic and potential energies of the system are expressed using these generalized coordinates or momenta, and the equations of motion can be readily set up, thus analytical mechanics allows numerous mechanical problems to be solved with greater efficiency than fully vectoral methods. Analytical mechanics is the foundation of many areas of theoretical physics, and has wide-ranging applications in engineering and simulation programs.
The Quantum World and the Expansion of the Universe - Cosmological Model by Vortices

Statistical Mechanics and Stochastic Thermodynamics
The theory of statistical mechanics is the best link we have between the imperceptible world of atoms and molecules and our common macroscopic experience. This textbook provides the fundamental rules and relationships of statistical mechanics. Through it, students will learn how to deduce the properties of materials from an underlying understanding of the behaviour of its constituent building blocks. The textbook covers the basics of systems at rest, as well as those directly manipulated. The former, also known as equilibrium statistical mechanics, is reviewed in the context of recent results in probability theory, with emphasis on solvation phenomena and phase transitions. The latter, nonequilibrium statistical mechanics, has seen tremendous advancement in the last few years, and is integrated into a textbook for the first time. These latter chapters emphasize rates of rare events like chemical reactions as well as single molecule experiments. Throughout the book, distinctions between heat and work, as well as notions of trajectory ensembles reflect the incorporation of stochastic thermodynamics into the modern language of statistical mechanics. Ideas of scaling, the concentration of measures, and generalized theories of ensemble equivalence represent the important contribution of the mathematics of large deviations.
Particles in the Dark Universe
This second edition of Particles in the Dark Universe has been substantially enhanced with several new chapters that delve into crucial aspects of particle physics in the Universe. These additions encompass the role of primordial black holes in the early universe, tracing their formation to decay, unification theories, a comprehensive historical overview of cosmological models, an extensive examination of the physics of the graviton, and an educational exploration of gravitational phenomena such as Unruh-type or Hawking radiation. Additionally, this edition incorporates 30 new exercises and provides a comprehensive presentation of inflationary models, along with a pedagogical insight into the mechanism of baryogenesis. Structured in a logical sequence, this book offers a thorough and instructional exploration of particle physics within the early universe. It initiates by elucidating the thermal history of the universe, delving into pivotal concepts like Big Bang nucleosynthesis, the cosmic microwave background (CMB), and inflation. Subsequently, it meticulously addresses both direct and indirect detection methods of dark matter, followed by an in-depth analysis of neutrino physics. The book further scrutinizes potential candidates for dark matter and their interactions. Designed for theoretical physicists engaged in particle physics within the universe, dark matter detection, astrophysical constraints, and those interested in models of inflation or reheating, this book also caters to astrophysicists involved in quantum field theory computations. It encompasses all essential elements required for computing various physical processes, providing mathematical tables, necessary thermodynamic functions for the early universe, and Feynman rules. Consequently, this book serves as an intersecting point between astrophysics, particle physics, and cosmology.
Lyotropic Liquid Crystals
This book aims to review the field of lyotropic liquid crystals from amphiphilic to colloidal systems, bridging the gap between the two worlds of lyotropics and thermotropics by showing that many of the features observed in standard thermotropic liquid crystals may also be observed in lyotropic systems and vice versa. Indeed, for a long time, lyotropic liquid crystals have been overshadowed by their thermotropic counterparts, mainly due to the potential for application of the latter in the display industry. This picture has somewhat shifted over the last decade, with numerous novel lyotropic systems having been discovered and formulated, bringing to light their importance in wider scientific research. For example, the understanding of viruses forming self-assembled ordered phases has largely increased as mineral liquid crystals and clays have experienced a renaissance leading to fundamental research and work on structure formation in nanotechnology. Similarly, nano-rods, nano-wires, nanotubes and 2D materials like graphene oxide and others have been shown to exhibit liquid crystalline behaviour, which may be exploited in self-assembly, drug delivery or biosensors. Cellulose nanocrystals have become an important and popular field of research. The self-assembly of short chain DNA fragments has led to liquid crystal behaviour previously thought to be impossible. Chromonics were shown to exhibit fascinating physical properties, and the combination of active fluids with liquid crystals has opened a whole new field of research to be explored - 'living liquid crystals'.
Nuclear Data
Nuclear structure has two extreme regimes: one where the nuclear structure is collective and driven by all the protons and neutrons acting coherently, and one where the nuclear structure is dominated by single nucleons. Here, we follow the latter "Independent-Particle Motion View" and see how far nuclear data agree with such a simple model.
Applications of Accelerators in the Quantum Technology Era
This book explores new experimental techniques and theoretical models to deepen an understanding of radiation effects and ion interaction processes in order to design materials for devices for the emerging quantum technology era.
Non-rotating Spherically-symmetric Blackhole Spacetimes
The book is aimed at describing spherically-symmetric non-rotating blackkhole spacetimes surrounded of media; the media considered are the Relativistic dusts, the Relativistic plasmas and the Relativistic gaseous materials. The General-Relativistic implementation established after the definition of the positions and of the velocities of the generic observer; the configurations are analytically calculated after the stress-energy tensor. The Relativistic-Astrophysical implementation is provided with after the description of the investigation of the phenomena which characterize the several blackhole environments: for these purposes, the Relativistic Jeans gas, the adiabatic perturbations of the perfect fluids and the 3-velocities perturbations of the gas are considered. The new behaviors are analytically written of the velocities. Furthermore, the paradigms of temperature-descending fluid, which characterize some of the events taking place in the corona of the AGN region of the supermassive blackholes are fixed: the new Landau-Lifshitz-Pitaevskii Magneto-Hydrodynamics of the pressure fluid is newly analytically found.
Lasing Without Inversion
The purpose of the book 'Lasing Without Inversion' is to investigate a few aspects of a novel laser known as lasing without inversion, carried out by the author during recent years, which aims to obtain an insight into the subject and these are discussed in detail. The interest in lasing without inversion (LWI) derives from the potential for low wavelength lasing and the interesting interplay between atoms and light coherence.
