Open Quantum Physics and Environmental Heat Conversion into Usable Energy
This volume presents a clear understanding of the quantum mechanics of particles with reference to the current understanding of theory of relativity, gravitation, and electromagnetism, including essential phenomena as spin, the graviton spin, black holes, and the quantum particle states in the extreme conditions of a black hole formation, and of the Schwarzschild boundary. The reader is introduced to the recent theory of the quantum particle dynamics as a distribution of matter propagating with the velocity of the waves. The text describes this distribution by a Fourier space-time series expansion, which we call the wave function. The subsequent chapters delve into the mechanics of quantum particles in a gravitational field, charged particles in a gravitational field and finally, the least action and matter-field dynamics in a gravitational field. The book also explains important rules in quantum mechanics such as the mass quantization rule, Dirac's formulation of the general theory of relativity, electromagnetic field theory, quantum particle interactions and more. The volume serves as a concise introduction to the complex topic of quantum particle mechanics for scholars involved in advanced physics courses.
Monopulse Measurement with Active Electronically Scanned Arrays (Aesas)
This book describes monopulse implemented with Active Electronically Scanned Arrays (AESAs). Both phase- and amplitude-comparison monopulse are addressed. Limitations imposed by AESAs and non-ideal performance due to quantization, vector modulator noise, and element failures are discussed. The author addresses monopulse using modern low-cost AESAs where the hardware is often non-ideal and where one must carefully balance cost and complexity. The relationship between AESA antenna gain and monopulse measurement is shown and is used to construct an accurate "first-principles" simulation of the monopulse measurement process including both Additive White Gaussian Noise and non-ideal hardware effects.For those unfamiliar with monopulse, this book discusses both the theory and implementation of monopulse for application in modern AESA antennas. For those familiar with the ideal performance of monopulse, the book shows the sensitivity of monopulse accuracy to non-ideal hardware implementations, particularly in AESAs. For those familiar with both, the book discusses Monte-Carlo techniques for simulating the measurement process to obtain realistic, non-ideal monopulse performance vs signal-to-noise ratio. And for those working in radar, the book explains the relationship between one-way monopulse and the monostatic radar case with two-way propagation utilizing the same antenna for both transmit and receive.Shows the relationship between monopulse theory and implementation in modern AESAs;Illustrates the relationship between AESA antenna gain and monopulse accuracy;Discusses the limitations of AESA hardware implementation on simultaneous sidelobe control and monopulse measurement.
Decoding Gravity, Time and Causality
Given in this book is the phenomenological description of a theory of Quantum Gravity which I call 'Dynamic General Relativity' without a sliver of complex mathematics.It is General Relativity reimagined. The theory explains what General Relativity means at the most fundamental level. Potential errors in Einstein's Special Relativity and General Relativity lie within the book with satisfactory corrections.Starting with GR, taking just a few assumptions from Loop Quantum Gravity and with just three additional assumptions i.e. 'Creation, Destruction and Entanglement', a rather complex theory can be constructed. General Relativity, Newtonian Dynamics, Modified Newtonian Dynamics (MOND) pop out of the theory effortlessly at appropriate levels.The theory almost effortlessly unifies Quantum Mechanics and General Relativity and can offer a potential bridge between Loop Quantum Gravity and String Theory, almost completely redefining how we look at higher dimensions and Strings.Definitions and explanations for poorly defined aspects of physics like inertia, kinetic energy, the relativity of time and space, wave-particle duality of light and matter and quantum superposition emerge out of it effortlessly.It can derive the causality of all the fundamental forces of nature and thus explain what causes phenomena like charge, attraction/repulsion, electromagnetic bonding, etc. It answers the fundamental questions like 'Why everything doesn't collapse under gravity?' or 'Why matter and antimatter did not annihilate each other at the time of creation?' and ultimately 'Why the universe exists?'.A must-read for every person or physicist who wishes to know the ultimate truth and is troubled by the enigmatic question, 'Why Newton's apple falls?'

Passive Optical Resonators for Next-Generation Attosecond Metrology
This book introduces readers to the development of a new generation of high pulse-repetition frequency instruments for multi-dimensional attosecond-resolution photoelectron spectroscopy (attosecond PES). It investigates the power scaling of femtosecond enhancement cavities for efficient intracavity high-harmonics generation (HHG). Further, it derives and verifies advanced resonator designs that feature large illuminated spots on all mirrors, which mitigate both intensity- and thermally-induced enhancement limitations.The dynamics of a high-finesse, passive resonator in the presence of a highly nonlinear optical process such as HHG are quantitatively investigated, both theoretically and experimentally. These investigations are instrumental in achieving the holistic optimization of the XUV source reported on here, which for the first time reached intracavity HHG conversion efficiencies comparable to those achieved in single-pass setups with a similar gas target.Coupling out the XUV beam from the enhancement cavity by purely geometric means, employing both the fundamental and higher-order transverse Gaussian modes, is studied. This offers the advantages of robustness, low distortion to the participating pulses, and photon-energy scalability. Last but not least, the author provides a range of proof-of-principle attosecond angle-resolved PES experiments.The book gives an outlook on the possible future development of cavity-enhanced HHG and an extensive discussion on the generation of isolated XUV attosecond pulses via intracavity wavefront rotation.
A Prelude to Quantum Field Theory
A concise, beginner-friendly introduction to quantum field theory Quantum field theory is a powerful framework that extends quantum mechanics in ways that are essential in many modern applications.

The result is an easy-to-use textbook that distills the most general properties of the theory without overwhelming beginning students with more advanced applications.Bridges quantum mechanics and quantum field theory, emphasizing analogies and differencesEmphasizes a "quantum field theoretical mindset" while maintaining mathematical rigorObtains quantum fields as the continuum limit of a quantized system of many particlesHighlights the correspondence between wave function--fundamental in quantum mechanics--and the formalism of second quantization used in quantum field theoryProvides a step-by-step derivation of Feynman rules for the perturbative study of interacting theoriesIntroduces students to renormalization, path integrals techniques, and moreDiscusses more modern topics like effective field theoriesIdeal for both undergraduate and graduate studentsProven in the classroom
Quantum Field Theory, as Simply as Possible
An exceptionally accessible introduction to quantum field theory Quantum field theory is by far the most spectacularly successful theory in physics, but also one of the most mystifying. This venerable subject provides the crucial bridge between the long established quantum mechanics and the still hypothetical string theory. Quantum Field Theory, as Simply as Possible provides an essential primer on the subject, giving readers the conceptual foundations they need to wrap their heads around one of the most important yet baffling subjects in physics. Quantum field theory grew out of quantum mechanics in the late 1930s and was developed by a generation of brilliant young theorists, including Julian Schwinger and Richard Feynman. Their predictions were experimentally verified to an astounding accuracy unmatched by the rest of physics. Quantum field theory unifies quantum mechanics and special relativity, thus providing the framework for understanding the quantum mysteries of the subatomic world. With his trademark blend of wit and physical insight, A. Zee guides readers from the classical notion of the field to the modern frontiers of quantum field theory, covering a host of topics along the way, including antimatter, Feynman diagrams, virtual particles, the path integral, quantum chromodynamics, electroweak unification, grand unification, and quantum gravity. A unique and valuable introduction for students and general readers alike, Quantum Field Theory, as Simply as Possible explains how quantum field theory informs our understanding of the universe, and how it can shed light on some of the deepest mysteries of physics.

Particular emphasis is given to recent hot topics concerning iron-based superconductors, both of fundamental nature and relevant for applications. The book is intended as a learning tool for researchers in the field, and serves as a guide providing inspiring examples of the use of coplanar resonator techniques to address key topics in the field of unconventional superconductivity.
Essay on Relative Gravity
Theory is theory by design. Object Oriented Design allows Theory to be extendable. Orion Daley's revolutionary new theory of Relative Gravity explains in an object oriented way how the universe is put together. The fundamental universe is viewed like a plasma of alternating currents. Symmetry is conserved through polymorphism of inherent properties. Given a wave length of some deep time, symmetry in properties is not at the exclusion of randomness. As derivatives, the four known forces: the Electro Strong and Weak, Electromagnetism and Gravity are considered to share symmetry where differentiated by their context. The relationship of dark and light matter is seen as that of impedance where particles to galaxies, or any other body between, are first viewed as manifolds having common and inherent properties. Particles can have opposite charge, and harmonics of vectors for strings with wavelengths subject to distortion. Bodies are considered skew-able and cumulative with respect to others within their context. Gravity is viewed as their fundamental relationship through superposition.
On Theories
A renowned philosopher's final work, illuminating how the logical empiricist tradition has failed to appreciate the role of actual experiments in forming its philosophy of science. The logical empiricist treatment of physics dominated twentieth-century philosophy of science. But the logical empiricist tradition, for all it accomplished, does not do justice to the way in which empirical evidence functions in modern physics. In his final work, the late philosopher of science William Demopoulos contends that philosophers have failed to provide an adequate epistemology of science because they have failed to appreciate the tightly woven character of theory and evidence. As a consequence, theory comes apart from evidence. This trouble is nowhere more evident than in theorizing about particle and quantum physics. Arguing that we must consider actual experiments as they have unfolded across history, Demopoulos provides a new epistemology of theories and evidence, albeit one that stands on the shoulders of giants. On Theories finds clarity in Isaac Newton's suspicion of mere "hypotheses." Newton's methodology lies in the background of Jean Perrin's experimental investigations of molecular reality and of the subatomic investigations of J. J. Thomson and Robert Millikan. Demopoulos extends this account to offer novel insights into the distinctive nature of quantum reality, where a logico-mathematical reconstruction of Bohrian complementarity meets John Stewart Bell's empirical analysis of Einstein's "local realism." On Theories ultimately provides a new interpretation of quantum probabilities as themselves objectively representing empirical reality.

Effective Medium Theory of Metamaterials and Metasurfaces
Metamaterials, including their two-dimensional counterparts, are composed of subwavelength-scale artificial particles. These materials have novel electromagnetic properties, and can be artificially tailored for various applications. Based on metamaterials and metasurfaces, many abnormal physical phenomena have been realized, such as negative refraction, invisible cloaking, abnormal reflection and focusing, and many new functions and devices have been developed. The effective medium theory lays the foundation for design and application of metamaterials and metasurfaces, connecting metamaterials with real world applications. In this Element, the authors combine these essential ingredients, and aim to make this Element an access point to this field. To this end, they review classical theories for dielectric functions, effective medium theory, and effective parameter extraction of metamaterials, also introducing front edge technologies like metasurfaces with theories, methods, and potential applications. Energy densities are also included.

Omnidirectional Slots Antenna
Omnidirectional antenna with high gain, low profile, vertical polarization, even CP polarization is very difficult to design, although it is from the dipole. In this book, a novel idea that the running wave in the coaxial wire is disturbed by the orthogonal slot array on the cylindrical metal shell is introduced, which radiates the CP wave in omni-direction. When feeding on two ends of the coaxial wire respectively, there will appear left hand circularly polarized (LHCP) omnidirectional radiation or right hand circularly polarized (RHCP) omnidirectional radiation. By introducing the T-shaped feed structure, the coaxial wire with slot array can conveniently produce the LHCP and RHCP radiation diversity with one end feeding. In the further, combining with the directional antenna, it will generate the pattern diversity in the half-sphere space. The antenna of the coaxial wire with slot array can further transform into conical CP beam antenna if the coaxial wire becomes into a conical frustum. By introducing the PIN diode into the slot, the antenna of the coaxial wire with slot array can radiate the reconfigurable directional beam by switching the states of the PIN diodes. By introducing a novel switchable microwave circuit, the omnidirectional /directional pattern switchable antenna can be realized easily.This book proposes a continues method to develop the potentialities of the omnidirectional antenna. And the readers can study the method or ideas of the omnidirectional slots antenna, even graft the CP or diversity methods to other antennae.

Quantum Photonics
Photonics is the discipline of electrons and photons working in tandem to create new physics, new devices and new applications. This textbook employs a pedagogical approach that facilitates access to the fundamentals of quantum photonics. Beginning with a review of the quantum properties of photons and electrons, the book then introduces the concept of their non-locality at the quantum level. It presents a determination of electronic band structure using the pseudopotential method, enabling the student to directly compute the band structures of most group IV, group III-V, and group II-VI semiconductors. The book devotes further in-depth discussion of second quantization of the electromagnetic field that describes spontaneous and stimulated emission of photons, quantum entanglement and introduces the topic of quantum cascade lasers, showing how electrons and photons interact in a quantum environment to create a practical photonic device.This extended second editionincludes a detailed description of the link between quantum photon states and the macroscopic electric field. It describes the particle qualities of quantum electrons via their unique operator algebra and distinguishable behavior from photons, and employs these fundamentals to describe the quantum point contact, which is the quantum analogue of a transistor and the basic building block of all nanoscopic circuits, such as electron interferometers.Pearsall's Quantum Photonics is supported by numerous numerical calculations that can be repeated by the reader, and every chapter features a reference list of state-of-the art research and a set of exercises. This textbook is an essential part of any graduate-level course dealing with the theory of nanophotonic devices or computational physics of solid-state quantum devices based on nanoscopic structures.
Advanced Laser and Competing Technologies Easily Explained
High power lasers and their applications in production technology have experienced a vivid development during the last decades and now offer improved performance of classical applications in cutting or welding. Processes that are used since a long time have been improved considerably, for instance hardening. More and more new applications have been developed for instance 3D-printing of metals or forming with laser assistance. Therefore, it is important for production engineers to understand the laser technology and explore how it can be used to enhance production speed, quality, and reduce cost.This book treats the basic principles underlying laser technology, long-time-used equipment and processes but also the most recent improvements and applications, then compares it with the competing conventional technologies. Each of these two parts is preceded by tutorials that inform the reader about the physical basis of the respective technologies. In addition, hazards of these technologies and respective protection are treated for both cases. The book concludes with a detailed comparison of competing technologies and lasers to give a prognosis on the future of lasers in manufacturing. It is written in a style that can be read by people without a broad physical basis and avoids the use of derivations and equations but explains all the material in an easily understandable way in simple words.
Lectures On Elementary Particles and Quantum Field Theory, Volume 1
The first volume of the Brandeis University Summer Institute lecture series of 1970 on theories of interacting elementary particles, consisting of four sets of lectures.Every summer since 1959 Brandeis University has conducted a lecture series centered on various areas of theoretical physics. The areas are sufficiently broad to interest a large number of physicists and the lecturers are among the original explorers of these areas.The 1970 lectures, presented in two volumes, are on theories of interacting elementary particles. The four lecturers of Volume 1, and the range of the topics they cover, are as follows: Stephen L. Adler (Institute for Advanced Study) on Perturbation Theory Anomalies: introduction and review of perturbation theory; the VVA triangle anomaly; absence of radiative corrections; generalizations of our results; connection between Ward identity anomalies and commutator (Bjorken-limit) anomalies; applications of the Bjorken limit; and breakdown of the Bjorken limit in perturbation theory.Stanley Mandelstam (University of California at Berkeley) on Dynamical Applications of the Veneziano formula for the four-point scalar amplitude; factorization; the operator formalism; Veneziano-type quark models; and higher-order Feynman-like diagrams. Steven Weinberg (Massachusetts Institute of Technology) on Dynamic and Algebraic Symmetries: Introduction; hadron electrodynamics; local symmetries; and chirality. Wolfhart Zimmermann (New York University) on Local Operator Products and Renormalization in Quantum Field Theory: introduction; renormalization; operator product expansions; and local field equations. The second volume contains lectures by Rudolf Haag on observables and fields, by Maurice Jacob on duality, by Michael Reed on non-Fock representations, and by Bruno Zumino on effective Lagrangians and broken symmetries.
How to Be a Quantum Mechanic
How to Be a Quantum Mechanic is an introduction to quantum mechanics at the upper-division level. It begins with wave-particle duality and ends with a brief introduction to the Dirac equation. Two attitudes went into its writing: Examples are the best way to get into a subject, and numbers and equations alone do not always sum to understanding. The author taught for 40 years at the University of California, Berkeley. He earned his Ph.D. at Berkeley, in experimental elementary-particle physics in the group led by Luis Alvarez.
Simply Schr繹dinger
Born in Vienna, Austria, Erwin Schr繹dinger (1887-1961) was the only child of a Catholic father and an Austrian-English Lutheran mother. He attended the University of Vienna, receiving his doctorate in 1910. For the next 45 years, he held positions at many different universities in Europe, the U.K., and the U.S., a result both of his antipathy to Nazism, as well as his unconventional lifestyle, which often involved living with multiple women at a time. After appointments at Oxford, Princeton, and the University of Graz in Austria, Schr繹dinger was invited in 1938 to help set up the Dublin Institute for Advanced Studies, where, from 1940 until his retirement in 1955, he served as the director of the School for Theoretical Physics. In addition to his groundbreaking work in physics-for which he received the Nobel Prize in 1933-Schr繹dinger had a lifelong interest in philosophy and Eastern religion, and his lectures and writings included discussions of such topics as consciousness, free will, and the nature of reality.In Simply Schr繹dinger, acclaimed science writer John Gribbin takes the measure of this singular scientist, who stands with Einstein, Heisenberg, and Dirac as one of the creators of a new scientific reality. While the focus is primarily on Schr繹dinger's particular contributions to quantum physics-including wave mechanics and wave-particle duality, as well as the famous feline-Gribbin also delves into Schr繹dinger's fascination with Eastern philosophy and the other distinctive traits that differentiated him from his peers and made him who he was.Written in a personable and accessible style that minimizes jargon and doesn't require a degree in physics, Simply Schr繹dinger is a fascinating introduction to one of the giants of the 20th century, who blazed his own trail in science and in life.

Accelerating and Vortex Laser Beams
This book gives insight into the theoretical backgrounds of optical vortices and their propagation in free space and simple optical systems. The author's theoretical analysis allows full comprehension of recent results and allows a bridge between the mentioned topics. For example, there is a solution for an accelerating beam propagating along an almost half-circle, obtained from a solution for an asymmetric vortex Bessel mode. And vice versa, there is a solution for an optical vortex with accelerating focusing, obtained from a solution for a two-dimensional accelerating Pearcey beam. The book is intended for graduate and postgraduate students studying optics or wave physics.

The book gives a concise but comprehensive introduction to theory, calculus, and typical experimental set-up used in magneto-optics. It includes a variety of practice problems with detailed solutions. The focus lies on the spectral range between near-infrared and near ultraviolet light because it is easily accessible in experiment using standard quartz optics.
Advancement of Selective Laser Melting by Laser Beam Shaping
Selective Laser Melting (SLM), also referred to as Laser Powder Bed Fusion (L-PBF), offers significant advantages for the manufacturing of complex, high-quality parts. However, its market share is still small compared to conventional manufacturing technologies. Major drawbacks hindering an industrial ramp-up are low productivity, high part costs and issues with quality and reproducibility. Comprehensive research has been done to overcome these challenges, but little attention has been paid to addressing them by optimizing the laser beam profile. Therefore, the author examines the effect of the laser beam profile on the productivity and process stability through both numerical and experimental investigations. The results show clear advantages an optimized laser beam profile offers.

Advanced Topics in Quantum Mechanics
Quantum mechanics is one of the most successful theories in science, and is relevant to nearly all modern topics of scientific research. This textbook moves beyond the introductory and intermediate principles of quantum mechanics frequently covered in undergraduate and graduate courses, presenting in-depth coverage of many more exciting and advanced topics. The author provides a clearly structured text for advanced students, graduates and researchers looking to deepen their knowledge of theoretical quantum mechanics. The book opens with a brief introduction covering key concepts and mathematical tools, followed by a detailed description of the Wentzel-Kramers-Brillouin (WKB) method. Two alternative formulations of quantum mechanics are then presented: Wigner's phase space formulation and Feynman's path integral formulation. The text concludes with a chapter examining metastable states and resonances. Step-by-step derivations, worked examples and physical applications are included throughout.
Development and Characterization of a Dispersion-Encoded Method for Low-Coherence Interferometry
This Open Access book discusses an extension to low-coherence interferometry by dispersion-encoding. The approach is theoretically designed and implemented for applications such as surface profilometry, polymeric cross-linking estimation and the determination of thin-film layer thicknesses. During a characterization, it was shown that an axial measurement range of 79.91 繕m with an axial resolution of 0.1 nm is achievable. Simultaneously, profiles of up to 1.5 mm in length were obtained in a scan-free manner. This marked a significant improvement in relation to the state-of-the-art in terms of dynamic range. Also, the axial and lateral measurement range were decoupled partially while functional parameters such as surface roughness were estimated. The characterization of the degree of polymeric cross-linking was performed as a function of the refractive index. It was acquired in a spatially-resolved manner with a resolution of 3.36 x 10-5. This was achieved by the developmentof a novel mathematical analysis approach.
