Download or read book The Quantum Vacuum written by Luciano Boi and published by JHU Press. This book was released on 2011-10-28 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: A vacuum, classically understood, contains nothing. The quantum vacuum, on the other hand, is a seething cauldron of nothingness: particle pairs going in and out of existence continuously and rapidly while exerting influence over an enormous range of scales. Acclaimed mathematical physicist and natural philosopher Luciano Boi expounds the quantum vacuum, exploring the meaning of nothingness and its relationship with physical reality. Boi first provides a deep analysis of the interaction between geometry and physics at the quantum level. He next describes the relationship between the microscopic and macroscopic structures of the world. In so doing, Boi sheds light on the very nature of the universe, stressing in an original and profound way the relationship between quantum geometry and the internal symmetries underlying the behavior of matter and the interactions of forces. Beyond the physics and mathematics of the quantum vacuum, Boi offers a profoundly philosophical interpretation of the concept. Plato and Aristotle did not believe a vacuum was possible. How could nothing be something, they asked? Boi traces the evolution of the quantum vacuum from an abstract concept in ancient Greece to its fundamental role in quantum field theory and string theory in modern times. The quantum vacuum is a complex entity, one essential to understanding some of the most intriguing issues in twentieth-century physics, including cosmic singularity, dark matter and energy, and the existence of the Higgs boson particle. Boi explains with simple clarity the relevant theories and fundamental concepts of the quantum vacuum. Theoretical, mathematical, and particle physicists, as well as researchers and students of the history and philosophy of physics, will find The Quantum Vacuum to be a stimulating and engaging primer on the topic.

Available in PDF, EPUB and Kindle. Book excerpt: In modern physics, the classical vacuum of tranquil nothingness has been replaced by a quantum vacuum with fluctuations of measurable consequence. In The Quantum Vacuum, Peter Milonni describes the concept of the vacuum in quantum physics with an emphasis on quantum electrodynamics. He elucidates in depth and detail the role of the vacuum electromagnetic field in spontaneous emission, the Lamb shift, van der Waals, and Casimir forces, and a variety of other phenomena, some of which are of technological as well as purely scientific importance. This informative text also provides an introduction based on fundamental vacuum processes to the ideas of relativistic quantum electrodynamics and quantum field theory, including renormalization and Feynman diagrams. Experimental as well as theoreticalaspects of the quantum vacuum are described, and in most cases details of mathematical derivations are included. Chapter 1 of The Quantum Vacuum - published in advance in The American Journal of Physics (1991)-was later selected by readers as one of the Most Memorable papers ever published in the 60-year history of the journal. This chapter provides anexcellent beginning of the book, introducing a wealth of information of historical interest, the results of which are carefully woven into subsequent chapters to form a coherent whole. - Does not assume that the reader has taken advanced graduate courses, making the text accessible to beginning graduate students - Emphasizes the basic physical ideas rather than the formal, mathematical aspects of the subject - Provides a careful and thorough treatment of Casimir and van der Waals forces at a level of detail not found in any other book on this topic - Clearly presents mathematical derivations
Download or read book An Introduction to Quantum Optics and Quantum Fluctuations written by Peter W. Milonni and published by Oxford University Press. This book was released on 2019 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an introduction to the quantum theory of light and its broad implications and applications. A significant part of the book covers material with direct relevance to current basic and applied research, such as quantum fluctuations and their role in laser physics and the theory of forces between macroscopic bodies (Casimir effects). The book includes numerous historical sidelights throughout, and approximately seventy exercises. The book provides detailed expositions of the theory with emphasis on general physical principles. Foundational topics in classical and quantum electrodynamics are addressed in the first half of the book, including the semiclassical theory of atom-field interactions, the quantization of the electromagnetic field in dispersive and dissipative media, uncertainty relations, and spontaneous emission. The second half begins with a chapter on the Jaynes-Cummings model, dressed states, and some distinctly quantum-mechanical features of atom-field interactions, and includes discussion of entanglement, the no-cloning theorem, von Neumann's proof concerning hidden variable theories, Bell's theorem, and tests of Bell inequalities. The last two chapters focus on quantum fluctuations and fluctuation-dissipation relations, beginning with Brownian motion, the Fokker-Planck equation, and classical and quantum Langevin equations. Detailed calculations are presented for the laser linewidth, spontaneous emission noise, photon statistics of linear amplifiers and attenuators, and other phenomena. Van der Waals interactions, Casimir forces, the Lifshitz theory of molecular forces between macroscopic media, and the many-body theory of such forces based on dyadic Green functions are analyzed from the perspective of Langevin noise, vacuum field fluctuations, and zero-point energy.

Available in PDF, EPUB and Kindle. Book excerpt: Book Description Demystifying the Akasha: Consciousness and the Quantum Vacuum Duality, including the spiritual/material and mind/body dichotomies, has been the basis of the Western paradigm for four hundred years, and has been blamed for major world problems. Meanwhile, in the East, nonduality has prevailed. While science is generally seen in opposition to nonduality, this book sets out to prove the compatibility of the scientifi c outlook and the spiritual nonduality of India by constructing a mathematical model of cosmic consciousness. The ideas and their history are presented non technically in Part One, while the full mathematical details are presented in Part Two. Ralph Abraham is Professor of Mathematics at the University of California at Santa Cruz, one of the pioneers of chaos theory. He is the author or coauthor of several math texts, including Foundations of Mechanics, Dynamics the Geometry of Behavior, and Chaos in Discrete Dynamical Systems. He has also written books on the history of math, philosophy, and the arts, such as Chaos, Creativity, and Cosmic Consciousness and The Evolutionary Mind. Sisir Roy is Professor of Theoretical Physics, Indian Statistical Institute, Kolkata. His field of interest covers foundations of quantum mechanics, cosmology, functional geometry and brain function. He has published more than 100 papers in peer reviewed international journals and nine research and edited monographs by Kluwer Academic, World Scientific etc. publishers. Praise for Demystifying the Akasha: Consciousness and the Quantum Vacuum "A key contribution to bringing the concept of the Akasha into the ambit of contemporary science, and relating it to our understanding of consciousness. A book for all serious students of cosmos and consciousness." --Dr. Ervin Laszlo, Author of Science and the Akashic Field
Download or read book Fast Light Slow Light and Left Handed Light written by P.W. Milonni and published by CRC Press. This book was released on 2004-11-30 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The propagation of light in dispersive media is a subject of fundamental as well as practical importance. In recent years attention has focused in particular on how refractive index can vary with frequency in such a way that the group velocities of optical pulses can be much greater or much smaller than the speed of light in vacuum, or in which the refractive index can be negative. Treating these topics at an introductory to intermediate level, Fast Light, Slow Light and Left-Handed Light focuses on the basic theory and describes the significant experimental progress made during the past decade. The book pays considerable attention to the fact that superluminal group velocities are not in conflict with special relativity and to the role of quantum effects in preventing superluminal communication and violations of Einstein causality. It also explores some of the basic physics at the opposite extreme of very slow group velocities as well as stopped and regenerated light, including the concepts of electromagnetically induced transparency and dark-state polaritons. Another very active aspect of the subject discussed concerns the possibility of designing metamaterials in which the refractive index can be negative and propagating light is left-handed in the sense that the phase and group velocities are in opposite directions. The last two chapters are an introduction to some of the basic theory and consequences of negative refractive index, with emphasis on the seminal work carried out since 2000. The possibility that "perfect" lenses can be made from negative-index metamaterials-which has been perhaps the most controversial aspect of the field-is introduced and discussed in some detail.

Download or read book Casimir Physics written by Diego Dalvit and published by Springer Science & Business Media. This book was released on 2011-06-30 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Casimir effects serve as primary examples of directly observable manifestations of the nontrivial properties of quantum fields, and as such are attracting increasing interest from quantum field theorists, particle physicists, and cosmologists. Furthermore, though very weak except at short distances, Casimir forces are universal in the sense that all material objects are subject to them. They are thus also an increasingly important part of the physics of atom-surface interactions, while in nanotechnology they are being investigated not only as contributors to ‘stiction’ but also as potential mechanisms for actuating micro-electromechanical devices. While the field of Casimir physics is expanding rapidly, it has reached a level of maturity in some important respects: on the experimental side, where most sources of imprecision in force measurements have been identified as well as on the theoretical side, where, for example, semi-analytical and numerical methods for the computation of Casimir forces between bodies of arbitrary shape have been successfully developed. This book is, then, a timely and comprehensive guide to the essence of Casimir (and Casimir-Polder) physics that will have lasting value, serving the dual purpose of an introduction and reference to the field. While this volume is not intended to be a unified textbook, but rather a collection of largely independent chapters written by prominent experts in the field, the detailed and carefully written articles adopt a style that should appeal to non-specialist researchers in the field as well as to a broader audience of graduate students.
Download or read book Zero Distance written by Danah Zohar and published by Springer Nature. This book was released on 2022 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: "When Danah Zohar first published the early ideas of her Quantum Management Theory in the late 1990's, she articulated a new paradigm, inspired by quantum physics, and began a major contribution to our search for a new management theory that can replace outdated Taylorism. Now, in ZERO DISTANCE, the most comprehensive account of her project, she outlines how the theory has been implemented through the revolutionary RenDanHeyi business model of China's Haier Group, and subsequently several other large companies. Zohar's suggestion that the Haier model also offers a new social and political model is thought provoking. This book is a significant addition to our continuing conversation about the best way to manage companies and other human social systems. I recommend it highly." - Gary Hamel, London Business School, Author of Humanocracy This open access book offers a new management meta-theory to replace Taylorism. It presents a new paradigm in management thinking and a new, practical organizational model for implementing it in our personal and working lives, in our companies, in our communities and nations, and in a sustainable global order. It will offer an understanding of why and how "thinking-as-usual" is failing both business and political leaders in these new times, and it will advocate new thinking and new management practices that are so radically new that they turn everything we have taken for granted inside out and upside down. This new management model is called "Quantum Management Theory", because it is rooted in the new paradigm bequeathed to us by quantum physics and its younger sibling, complexity science. Danah Zohar is a physicist, philosopher, and management thought leader. She is a Visiting Professor at Tsinghua University's School of Economics and Management and a Visiting Professor at the China Academy of Art.
Download or read book Quantum Reality and Theory of nya written by Siddheshwar Rameshwar Bhatt and published by Springer. This book was released on 2019-03-30 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with expounding the nature of Reality as it is understood in contemporary times in Quantum Physics. It also explains the classical Indian theory of Śūnya in its diverse facets. Thereafter it undertakes comparison between the two which is an area of great topical interest. It is a cross-disciplinary study by erudite Indian and western scholars between traditional Indian knowledge system and contemporary researches in Physical sciences. It points out how the theory of ‘Śūnyatā has many seminal ideas and theories in common with contemporary Quantum Physics. The learned authors have tried to dissolve the “mysteries” of Quantum Physics and resolved its “weird paradoxes” with the help of theory of Śūnyatā. The issue of non-separability or entanglement has been approached with the help of the Buddhist theory of Pratītyasamutpāda. The paradoxical situation of “wave-particle duality” has been explained with the help of Upaniṣadic theory of complementarity of the two opposites. The measurement problem represented by “Schrodinger’s cat” has been dealt with by resorting to two forms of the calculation of probabilities. Some writers have argued for Śūnyatā-like non-essentialist position to understand quantum reality. To make sense of quantum theory some papers provide a happy symbiosis of technical understanding and personal meditative experience by drawing multifarious parallels. This book will be of interest to philosophically inclined physicists and philosophers with interest in quantum mechanics.

Download or read book Quantum Electrodynamics written by E.S. Fradkin and published by Springer. This book was released on 2011-12-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a systematic analysis of the formalisms of quantum electro dynamics in the presence of an intense external field able to create pairs from the vacuum, and thereby violate the stability of the latter. The approach developed is not specific to quantum electrodynamics, and can equally well be applied to any quantum field theory with an unstable vacuum. It should be noted that only macroscopic external fields are considered, whereas problems associated with the superstrong Coulomb (micro) field are not treated. As a rule, the discussion is confined to those details of the formalism and calculations that are specific to the instability property. For instance, renormalization is not discussed here since, in practical calculations, it is carried out according to standard methods. The presentation is based mainly on original research undertaken by the authors. Chapter 1 contains a general introduction to the problem. It also presents some standard information on quantum electrodynamics, which will be used later in the text. In addition, an interpretation of the concept of an external field is given, and the problems that arise when one tries to keep the interaction with the external field exactly are discussed. In Chapter 2, the perturbation expansion in powers of the radiative interac tion is developed for the matrix elements of transition processes, taking the arbitrary external field into account exactly.

Download or read book Faster Than Light written by H. David Froning, Jr. and published by SCB Distributors. This book was released on 2019-11-12 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: An amazing book on faster than light flight! H. David Froning, a 30-year veteran engineer who worked on several designs for future space travel propulsion, gives us this exceptional compilation of his discoveries, struggles and experiences in the realm of faster than light space travel. Central to the concept of faster than light travel is that the vacuum of space itself (the spacetime metric) can be utilized in propulsion systems. “Engineering the vacuum,” as this is called, involves discovering how space can be altered to provide energy/thrust for future spacecraft. Packed with diagrams, some of which show how, as a starship accelerates away from Earth, it disappears and reappears in only seconds. But during these seconds of disappearance, the ship, in effect, leaps high above space-time and over stupendous distances to reach speeds that are billions of times greater than light-speed. Lots of great material on quantum vacuum power, anti-gravity propulsion effects, the velocity of light in spacetime altered regions, effective mass in spacetime-altered regions, warp drives, and tons more!

Available in PDF, EPUB and Kindle. Book excerpt: The subject of this book is the Casimir effect, a manifestation of zero-point oscillations of the quantum vacuum resulting in forces acting between closely spaced bodies. For the benefit of the reader, the book assembles field-theoretical foundations of this phenomenon, applications of the general theory to real materials, and a comprehensive description of all recently performed measurements of the Casimir force with a comparison between experiment and theory. There is an urgent need for a book of this type, given the increase of interest in forces originating from the quantum vacuum. Numerous new results have been obtained in the last few years which are not reflected in previous books on the subject, but which are very promising for fundamental science and nanotechnology. The book is a unique source of information presenting a critical assessment of all the main results and approaches from hundreds of journal papers. It also outlines new ideas which have not yet been universally accepted but which are finding increasing support from experiment.
