The Quantum Theory of Light
Author: R. LoudonThe Quantum Theory of Light
Author: Rodney LoudonPublisher: Oxford University Press, USA
ISBN:
Category : Science
Languages : en
Pages : 416
Book Description
This third edition, like its two predecessors, provides a detailed account of the basic theory needed to understand the properties of light and its interactions with atoms, in particular the many nonclassical effects that have now been observed in quantum-optical experiments. The earlier chapters describe the quantum mechanics of various optical processes, leading from the classical representation of the electromagnetic field to the quantum theory of light. The later chapters develop the theoretical descriptions of some of the key experiments in quantum optics. Over half of the material in this third edition is new. It includes topics that have come into prominence over the last two decades, such as the beamsplitter theory, squeezed light, two-photon interference, balanced homodyne detection, travelling-wave attenuation and amplification, quantum jumps, and the ranges of nonlinear optical processes important in the generation of nonclassical light. The book is written as a textbook, with the treatment as a whole appropriate for graduate or postgraduate students, while earlier chapters are also suitable for final-year undergraduates. Over 100 problems help to intensify the understanding of the material presented.

The Electromagnetic Origin of Quantum Theory and Light
Author: Dale Mills GrimesPublisher: World Scientific
ISBN: 9812389253
Category : Science
Languages : en
Pages : 437
Book Description
This book resolves fundamental questions of quantum theory and offers arguably the strongest evidence yet in support of string theory. It is essential reading for everyone in physics, physical mathematics, and the philosophy of science. The authors model electrons as an ensemble of strings subject to the laws of classical statistical mechanics. This model shows the Schrodinger equation to be the low speed descriptor of equilibrium and near-equilibrium states but not of quantum jumps. Like other statistical systems, the electron ensemble passes through all possible intrinsic states. As a high energy eigenstate electron ensemble passes through an appropriate structure, it regeneratively produces an encompassing standing energy field. Regenerative field buildup enables the electron to be a radiative band pass filter: it is an efficient radiator at the buildup frequency and phase, but all other frequencies and phases are blocked. When a matching external field trigger is applied depending upon therelative phasings, the standing energy is either absorbed or emitted with full directivity.
Quantum Physics of Light and Matter
Author: Luca SalasnichPublisher: Springer
ISBN: 3319529986
Category : Science
Languages : en
Pages : 244
Book Description
This compact but exhaustive textbook, now in its significantly revised and expanded second edition, provides an essential introduction to the field quantization of light and matter with applications to atomic physics and strongly correlated systems. Following an initial review of the origins of special relativity and quantum mechanics, individual chapters are devoted to the second quantization of the electromagnetic field and the consequences of light field quantization for the description of electromagnetic transitions. The spin of the electron is then analyzed, with particular attention to its derivation from the Dirac equation. Subsequent topics include the effects of external electric and magnetic fields on the atomic spectra and the properties of systems composed of many interacting identical particles. The book also provides a detailed explanation of the second quantization of the non-relativistic matter field, i.e., the Schrödinger field, which offers a powerful tool for the investigation of many-body problems, and of atomic quantum optics and entanglement. Finally, two new chapters introduce the finite-temperature functional integration of bosonic and fermionic fields for the study of macroscopic quantum phenomena: superfluidity and superconductivity. Several solved problems are included at the end of each chapter, helping readers put into practice all that they have learned.
Einstein and the Quantum
Author: A. Douglas StonePublisher: Princeton University Press
ISBN: 0691168563
Category : Science
Languages : en
Pages : 344
Book Description
The untold story of Albert Einstein's role as the father of quantum theory Einstein and the Quantum reveals for the first time the full significance of Albert Einstein's contributions to quantum theory. Einstein famously rejected quantum mechanics, observing that God does not play dice. But, in fact, he thought more about the nature of atoms, molecules, and the emission and absorption of light—the core of what we now know as quantum theory—than he did about relativity. A compelling blend of physics, biography, and the history of science, Einstein and the Quantum shares the untold story of how Einstein—not Max Planck or Niels Bohr—was the driving force behind early quantum theory. It paints a vivid portrait of the iconic physicist as he grappled with the apparently contradictory nature of the atomic world, in which its invisible constituents defy the categories of classical physics, behaving simultaneously as both particle and wave. And it demonstrates how Einstein's later work on the emission and absorption of light, and on atomic gases, led directly to Erwin Schrödinger's breakthrough to the modern form of quantum mechanics. The book sheds light on why Einstein ultimately renounced his own brilliant work on quantum theory, due to his deep belief in science as something objective and eternal.

ISBN: 3319051792
Category : Science
Languages : en
Pages : 195
Book Description
The book gives an introduction to the field quantization (second quantization) of light and matter with applications to atomic physics. The first chapter briefly reviews the origins of special relativity and quantum mechanics and the basic notions of quantum information theory and quantum statistical mechanics. The second chapter is devoted to the second quantization of the electromagnetic field, while the third chapter shows the consequences of the light field quantization in the description of electromagnetic transitions. In the fourth chapter it is analyzed the spin of the electron, and in particular its derivation from the Dirac equation, while the fifth chapter investigates the effects of external electric and magnetic fields on the atomic spectra (Stark and Zeeman effects). The sixth chapter describes the properties of systems composed by many interacting identical particles by introducing the Hartree-Fock variational method, the density functional theory and the Born-Oppenheimer approximation. Finally, in the seventh chapter it is explained the second quantization of the non-relativistic matter field, i.e. the Schrodinger field, which gives a powerful tool for the investigation of many-body problems and also atomic quantum optics. At the end of each chapter there are several solved problems which can help the students to put into practice the things they learned.
Quantum Aspects of Life

Pages : 468
Book Description
This book presents the hotly debated question of whether quantum mechanics plays a non-trivial role in biology. In a timely way, it sets out a distinct quantum biology agenda. The burgeoning fields of nanotechnology, biotechnology, quantum technology, and quantum information processing are now strongly converging. The acronym BINS, for Bio-Info-Nano-Systems, has been coined to describe the synergetic interface of these several disciplines. The living cell is an information replicating and processing system that is replete with naturally-evolved nanomachines, which at some level require a quantum mechanical description. As quantum engineering and nanotechnology meet, increasing use will be made of biological structures, or hybrids of biological and fabricated systems, for producing novel devices for information storage and processing and other tasks. An understanding of these systems at a quantum mechanical level will be indispensable. Contents:Foreword (Sir R Penrose)Emergence and Complexity:A Quantum Origin of Life?

Category : Science
Languages : en
Pages : 78
Book Description
Space curves around you, time slows down, particles are waves, a cat is both alive and dead. What's going on? It all starts to make sense when we untangle the universe with this clear and enlightening book. Day-dreamers and deep-thinkers, these are the concepts that will send your mind wandering to new places with a deeper understanding of the natural world. Physics has always been a tricky subject for the general public. Millions are fascinated by the laws of the physical world, but there has been a lack of books written specifically for general readers. The Universe Untangled is for those who are curious; yet do not have an extensive mathematical background. It uses images, analogies and comprehensible language to cover popular topics of interest including the evolution of the universe, fundamental forces and particle interactions, the nature of space and time according to Special and General Relativity, the ideas of Quantum Mechanics and the quest for knowing the unknown. The Universe Untangled is a unique book because it is written by an author whose career has been built on making science accessible to all. She has contributed to the design and content production of educational games, professional development courses, and science workbooks. In essence, this is not a book written by a physicist for other physicists. It is written by an educator who cares only about sharing her passion for science with others.
