Electrically Driven Quantum Dot Based Single-Photon Sources
Semiconductor quantum optics is on the verge of moving from the lab to real world applications. When stepping from basic research to new technologies, device engineers will need new simulation tools for the design and optimization of quantum light sources, which combine classical device physics with cavity quantum electrodynamics. This thesis aims to provide a holistic description of single-photon emitting diodes by bridging the gap between microscopic and macroscopic modeling approaches. The central result is a novel hybrid quantum-classical model system that self-consistently couples semi-classical carrier transport theory with open quantum many-body systems. This allows for a comprehensive description of quantum light emitting diodes on multiple scales: It enables the calculation of the quantum optical figures of merit together with the simulation of the spatially resolved current flow in complex, multi-dimensional semiconductor device geometries out of one box. The hybrid system is shown to be consistent with fundamental laws of (non-)equilibrium thermodynamics and is demonstrated by numerical simulations of realistic devices.

Genetic Codes of the Artificially-Intelligent Multiverse
This book describes basic principles of the Artificially-Intelligent Multiverse (AIM) theory. Its first goal is to describe genetic codes of 4D spiral spacetimes called toryx and helyx capable of serving as prime elements of the Multiverse. Our Universe belongs to the spacetime level L1 of the Multiverse with its four more spacetime levels L2 through L5 containing materials that are progressively much lighter, stronger, contain much more energy, and able to emit and absorb radiation propagating with velocities much faster than velocity of light. The second challenging goal of the AIM theory is to provide an answer to a longstanding question: What is the purpose of human beings on a cosmic scale? To discover that purpose, the theory combines the unique spacetime properties of toryx and helyx with a unique capability of human beings to invent and implement the artificially-intelligent control systems increasing significantly their biologically-based capabilities. Currently, the Multiverse is governed by rigid laws of motion and does not have any control system preventing its celestial bodies from collisions. As the Multiverse becomes overcrowded a probability of their mutual destructions increases. A unified purpose of human beings is to sustain the existence of entire Multiverse by making it Artificially-Intelligent. Notably, it took billions of years to create the planet Earth as an incubator equipped with atmosphere, water, soil and energy resources necessary for existence of upcoming human beings. Thanks to their exponentially-expanding capabilities, the human being are now capable to develop the first generation of artificial intelligence in the form of drones surviving in hostile environment of outer space located outside of their incubator. Their survival is now dependent on thousands of satellites orbiting the Earth. They no longer wait passively for another huge asteroid to ram into the Earth and destroy most of its life but monitor the upcoming asteroids and developing the systems preventing the upcoming disaster. To achieve their unified purpose, the human beings have to start to think cosmically and to adjust accordingly their social, political, educational, judicial and economic systems.
God and Quantum Physics
Physics cannot show that a corporal, godlike figure exists in the universe. However, the major religions of the world, especially Christianity, describe God as a spiritual energy and not corporal. Quantum physics says there exists a universal energy that has the attributes of God. This energy has consciousness and creativity. All matter is composed of this energy. This energy was responsible for the Big Bang. Professor emeritus William Tiller, a physicist at Stanford University, has shown this energy can interact with human consciousness. This book takes you through a non-mathematical proof of the physics of these assertions.
Nico Bloembergen
This biography is a personal portrait of one of the best-known Dutch physicists, Nicolaas Bloembergen. Born in 1920 in Dordrecht, Bloembergen studied physics in Utrecht, leaving after World War II for the United States, where he became an American citizen in 1958. At Harvard University, he pioneered nuclear magnetic resonance (NMR, used in chemistry and biology for structure identification; moreover leading to MRI), laser theory and nonlinear optics. In 1978 he was awarded the Lorentz Medal for his contribution to the theory of nonlinear optics (used in fiber optics), and in 1981 he received the Nobel Prize for physics, along with Arthur Schawlow and Kai Siegbahn. The book is based on numerous conversations with Nicolaas Bloembergen himself, his wife Deli Brink, his family, and colleagues in science. It describes his childhood and study in Bilthoven and Utrecht, the first postwar years at Harvard, the discoveries of masers and lasers, and the award of the Nobel Prize.It also delves into Bloembergen's involvement in American politics, particularly his role in Ronald Reagan's controversial "Star Wars" program.

Multiverse Theories
If the laws of nature are fine-tuned for life, can we infer other universes with different laws? How could we even test such a theory without empirical access to those distant places? Can we believe in the multiverse of the Everett interpretation of quantum theory or in the reality of other possible worlds, as advocated by philosopher David Lewis? At the intersection of physics and philosophy of science, this book outlines the philosophical challenge to theoretical physics in a measured, well-grounded manner. The origin of multiverse theories are explored within the context of the fine-tuning problem and a systematic comparison between the various different multiverse models are included. Cosmologists, high energy physicists, and philosophers including graduate students and researchers will find a systematic exploration of such questions in this important book.
Electromagnetic Optics of Thin-Film Coatings
Three experts in the field of thin-film optics present a detailed and self-contained theoretical study of planar multilayers and how they can be effectively exploited in both traditional and modern applications. Starting with a discussion of the relevant electromagnetic optics, the fundamental optical properties of multilayers are introduced using an electromagnetic approach based on a direct solving of Maxwell's equations by Fourier transforms. This powerful approach is illustrated through the comprehensive description of two of the most important phenomena in multilayers, i.e. giant field enhancement in dielectric stacks and light scattering from thin-film optical filters. The same approach is extended to the description of the operation of planar microcavities and the balance of energy between radiated and trapped light. This book will be valuable to researchers, engineers and graduate students with interests in nanophotonics, optical telecommunications, observational astronomy and gravitational wave detection.

But is it really the light that moves?
The important physician Victor F. Weisskopf said: "the most important problems in physics can be explained in simple terms, without using complex equations or mathematical demostrations" . And this is the real message of the present book, leaving to others the task of confirming or invalidating it with more specialist considerations what I wrote here. I just wanted to stimulate the fantasy, treating old problems from an uncommon point of view and, up to now, I have not found contradictions in what I stated.
Theory of Thermodynamic Measurements of Quantum Systems Far from Equilibrium
This thesis presents several related advances in the field of nonequilibrium quantum thermodynamics. The central result is an ingenious proof that the local temperature and voltage measurement in a nonequilibrium system of fermions exists and is unique, placing the concept of local temperature on a rigorous mathematical footing for the first time. As an intermediate step, a proof of the positivity of the Onsager matrix of linear response theory is given -- a statement of the second law of thermodynamics that had lacked an independent proof for 85 years. A new experimental method to measure the local temperature of an electron system using purely electrical techniques is also proposed, which could enable improvements to the spatial resolution of thermometry by several orders of magnitude. Finally, a new mathematically-exact definition for the local entropy of a quantum system in a nonequilibrium steady state is derived. Several different measures of the local entropy are discussed, relating to the thermodynamics of processes that a local observer with varying degrees of information about the microstates of the system could carry out, and it is shown that they satisfy a hierarchy of inequalities. Proofs of the third law of thermodynamics for generic open quantum systems are presented, taking into account the entropic contribution due to localized states. Appropriately normalized (per-state) local entropies are defined and are used to quantify the departure from local equilibrium.
Maxwell’s equation in quantum physics
Quantum physics differs from classical physics in the methods of study, and both of them consider the methods of the opposite side unacceptable for themselves. The author proposes the solution of some problems that are the privilege of quantum physics, using the methods of classical physics. At the same time, the author does not introduce any new postulates, but uses one and only tool, which is recognized by both physicists - the Maxwell system of equations. Strong interactions, atomic model, elementary particles, vacuum structure, electric charge, static electric field, electric current are considered.
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.
THE MICROWAVE DELUSION - Why ’Smart’ Wireless Means We Are Dying Younger in Poorer Health and Endangering the Wellbeing of Our Children
The Microwave Delusion tells how one highly successful UK business leader's experience of the damaging health effects of microwave radiation has become part of an international campaign to hold the mobile phone industry to account for its defective safety practices. This book charts industry and government collusion versus the rise of independent science, leading to campaigns and legal judgements in many countries. It proposes that the roll out of 5G in its present form endangers hundreds of millions of people of all ages. As one independent scientist says: 'We are taking risks that no rational society on earth should take.'

The Copenhagen Network
This book is a historical analysis of the quantum mechanical revolution and the emergence of a new discipline from the perspective, not of a professor, but of a recent or actual Ph.D. student just embarking on an uncertain academic career in economically hard times. Quantum mechanics exploded on to the intellectual scene between 1925 and 1927, with more than 200 publications across the world, the majority of them authored by young scientists under the age of 30, graduate students or postdoctoral fellows. The resulting theory was a collective product that no single authority could claim, but it had a major geographical nod - the Copenhagen Institute of Theoretical Physics - where most of the informal, pre-published exchange of ideas occurred and where every participant of the new community aspired to visit. A rare combination of circumstances and resources - political, diplomatic, financial, and intellectual - allowed Niels Bohr to establish this "Mecca" of quantum theory outside of traditional and more powerful centres of science. Transitory international postdoctoral fellows, rather than established professors, developed a culture of research that became the source of major innovations in the field. Temporary assistantships, postdoctoral positions, and their equivalents were the chief mode of existence for young academics during the period of economic crisis and post-WWI international tensions. Insecure career trajectories and unpredictable moves through non-stable temporary positions contributed to their general outlook and interpretations of the emerging theory of quantum mechanics. This book is part of a four-volume collection addressing the beginnings of quantum physics research at the major European centres of G繹ttingen, Copenhagen, Berlin, and Munich; these works emerged from an expansive study on the quantum revolution as a major transformation of physical knowledge undertaken by the Max Planck Institute for the History of Science and the Fritz HaberInstitute (2006-2012).

Children of Light
We associate light with the radiant beams that make the world visible to us. But the visible spectrum is only a tiny percentage of an electromagnetic spectrum that extends unimaginably far in both directions. And, as biologist Michael Denton carefully documents, that tiny band of visual light is crucial to life on Earth. In Children of Light, Denton elucidates the miraculous convergence of properties on the tiny band we call the visible spectrum that has allowed intelligent life to flourish on Earth. Follow the journey of light as it beams down from our Sun, through the protective blanket of our atmosphere, to the Earth. Once here, it powers photosynthesis and unlocks the oxygen needed for life. It allows the high-acuity vision that led us to civilization and technology. Light is just one more part of the epic story of our fine-tuned universe, fit for us to flourish here and come to understand it. This book is the third book in the Privileged Species series, which also includes The Wonder of Water and Fire-Maker.

All this and more is answered in this extraordinary conversation.Pax self-introduces as the "Divine Universe" and "God being" and has important information to share with humanity regarding planetary repair and environmental healing. This message often reads like an adventure and addresses world peace and unity and pollution and anthropogenic climate change in a way that is entertaining, solution-based, and enlightening.This particular portion of text, Pax and the Next Evolutionary Leap, constitutes one of eight volumes that together make up the book titled Do Unto Earth. In this volume, author and journalist Penelope Jean Hayes poses questions to Pax, channeled by intuitive Carole Serene Borgens, about the replacement to crude oil and the fuel for interstellar travel at lightspeed, communication through thought power and consciousness, remote viewing and more.
Was Ist Real?
Die Quantenphysik geh繹rt zu den gr繹?ten wissenschaftlichen Errungenschaften der Menschheit - dar羹ber sind sich Physiker einig. Die Frage nach der Interpretation der Quantenmechanik w羹rde allerdings in einer Pr羹gelei enden. Dieses Buch erz瓣hlt die packende Geschichte des Kampfes der Ideen und der mutigen Wissenschaftler, die es wagten, f羹r die Wahrheit einzutreten.Ein Jahrhundert lang sind die meisten Physiker der Kopenhagener Deutung von Niels Bohr gefolgt und haben Fragen 羹ber den Realit瓣tsbegriff in der Quantenphysik als bedeutungslos abgetan. Obwohl eine der popul瓣rsten Deutungen, ist sie nur ein Mischmasch aus schlechter Argumentation und der Angewohnheit, sich selbst als den einen Beobachter auszuzeichnen. Aber warum hat sie so lange Bestand? Weil Bohrs Studenten sein Verm瓣chtnis energisch verteidigten und die Physikgemeinde sich lieber praktischen Experimenten als philosophischen Diskussionen widmete. Das Resultat: Lange Zeit bedeutete ein Infragestellen des Status quo den wissenschaftlichen Ruin. Und doch haben Physiker wie John Bell, David Bohm und Hugh Everett von den 1920er Jahren bis heute beharrlich nach der wahren Bedeutung der Quantenmechanik gesucht: Bell mit dem Stift und seiner bei?enden Kritik, Bohm mit seiner sturen Geringsch瓣tzung des Status quo, Everett mit seiner schelmischen Art. Was ist real? ist die unbekannte Geschichte dieser ketzerischen Denker, die das Establishment dazu herausforderten, die Quantenphysik und die Natur der Wirklichkeit neu zu 羹berdenken.Der AutorAdam Becker ist Wissenschaftsautor.

Finite Mathematics as the Foundation of Classical Mathematics and Quantum Theory
This book delves into finite mathematics and its application in physics, particularly quantum theory. It is shown that quantum theory based on finite mathematics is more general than standard quantum theory, whilst finite mathematics is itself more general than standard mathematics.As a consequence, the mathematics describing nature at the most fundamental level involves only a finite number of numbers while the notions of limit, infinite/infinitesimal and continuity are needed only in calculations that describe nature approximately. It is also shown that the concepts of particle and antiparticle are likewise approximate notions, valid only in special situations, and that the electric charge and baryon- and lepton quantum numbers can be only approximately conserved.
The Planck-Einstein Breakthrough
The aim of the book is to explain why classical mechanics and classical electrodynamics were 'refuted' almost simultaneously at the beginning of the XX-th century. It is contended that the Quantum and the Relativistic revolutions were simultaneous since they had the common origin - the clash between the fundamental theories of the second half of the XIX-th century that constituted the 'body' of Classical Physics. The revolution's most dramatic turning point was Einstein's 1905 light quantum paper.Though Einstein's efforts sprung out of Max Planck's pioneering attempts to comprehend electromagnetic phenomena through the lenses of conceptual structures of statistical thermodynamics. It was Planck, who clearly realized the cross-contradiction between 'the physics of material bodies' and 'the physics of the ether' and outlined the sketch of its withdrawal: the paradigms 'must be modified to remain compatible'. And it was Planck who took the first step in modifying the physics of the ether and contending that 'not only matter itself but also the effects radiated from matter possess discontinuous properties'. Einstein's part consisted in that he took the second step in modifying the second component of the encounter - the physics of material bodies.Einstein's foolhardy light quanta hypothesis and distinctive special theory of relativity turn out to be mere milestones of the unwinding of Maxwellian electrodynamics and statistical thermodynamics reconcilement research program. The notorious conception of luminiferous ether was a substantial obstacle for Einstein's wayward statistical thermodynamics in which the pivotal lead was played by flagrant light quanta paper. Einstein was aware that his enticing light quanta hypothesis was too audacious to be taken literally and he laid out his version of 'electrodynamics of moving bodies' in a markedly Machian/ Duhemian, phenomenological way. As a result of the revision of the second scientific revolution key episode, the arguments are exhibited in favor of the necessity to modify the history of the genesis of general relativity; correspondingly, the process of unification of electromagnetic and weak interactions that took place in the second half of the XX-th century is scrutinized. Eventually, the encounter and interpenetration of the two dominating research traditions of modern physics - that of general relativity and quantum field theory - is elicited.
Multi-Time Wave Functions
The natural generalization of the quantum-mechanical N-particle wave function to relativistic space-time is a function of N space-time points, and thus of N time variables. This book, based on a collection of lectures given at a spring school in T羹bingen in 2019, provides an accessible and concise introduction to the recent development of the theory of multi-time wave functions, their use in quantum field theory, their relation to detection probabilities, and the mathematical question of consistency of their time evolution equations. The book is intended for advanced students and researchers with an interest in relativity and quantum physics.

EMC for Installers
The integration of electronics in large systems and installations steadily increases, consider for example the emergence of the Industrial Internet of Things. Power consumption decreases while the operating speed increases making equipment potentially more vulnerable for interference. The responsibility of the installer is shifting towards that of the system integrator, requiring more in-depth knowledge to achieve and maintain EMC during the technical and economical lifespan of the system or installation and the distinction between both diminishes.EMC for Installers: Electromagnetic Compatibility of Systems and Installations combines an integral risk based approached to EMC design and management with robust technical measures. Written by two experts, who both started nearly three decades ago in EMC, it provides guidance to those new in the field and servers as reference to those with experience. The book starts with the basic concept of EMC and evolves gradually towards more difficult topics. Particular attention is given to grounding concepts and the protection of cabling and wiring. This book puts a strong focus on passive means that are widely available for each installer: cable conduits used for cable routing can be exploited for significant improvement of the EMC-behavior of the system or installation. In addition, it will be explained how to use standard metallic enclosures to enhance the EMC-performance. For most demanding situations shielded rooms and shielding cabinets are explained. This book describes pre-compliance and full-compliance testing tailored to large systems. Templates and checklists are provided for both risk and management and test management. Electromagnetic compatibility explained as simple as possible, without over-simplifying. Practical approach, with hands-on demonstrations based on an example installation.

Quarks and Leptons from Orbifolded Superstring
This book is a guide for all those who want to explore the standard model using string theory. The approach pursued is "halfway" between a textbook and advanced research work and, accordingly, the book will allow both graduate students and particle phenomenologists to easily get acquainted with this fascinating field.In this new edition the authors report on the status quo of the standard model following the discovery of the Higgs Boson, as well as the latest results concerning physics beyond the standard model. They present a formal introduction to string orbifolds and explain in detail how the massless states and the Kaluza-Klein spectra can be derived from the partition function. In turn, they provide an overview of orbifold phenomenology, by introducing the key aspects of string orbifolds in the context of SUSY standard models. In closing, the authors discuss the Grand Unified Theories (GUTs) from orbifolds and share key concepts regarding Calabi-Yau compactifications, M-theory and F-theory.
