Available in PDF, EPUB and Kindle. Book excerpt: The subject of this book emerged from a series of lectures that the author gave at the Department of Physics of the University of North Texas during the 1992 Spring Semester, and reflects the vivacious discussions that he has been having with the students and the co-workers attending this course. The main conclusion of these discussions was that the major tenet of the "conservative" physicists, that classical physics must be recovered from quantum mechanics by adopting the statistical perspective of Gibbs, implying by necessity a Gibbs ensemble of Universes as well as a Gibbs ensemble of observers, is not satisfactory. It is actually as unsatisfactory as the dominant approaches to irreversibility. The book examines the current approaches to irreversibility, in classical and quantum physics, and shows that an objective theory of irreversibility does not exist yet, and that all the current theories of irreversibility share with quantum mechanics elements of subjectivity, making crucial the role played by the observer. In addition to the traditional quantum mechanical paradoxes, concerning the quantum theory of measurement, the book also discusses the new difficulties that the physics of chaos is causing to the widely accepted correspondence principle, and suggests that the Boltzmann dream, the dream that the fracture between dynamics and thermodynamics might be healed, cannot become true within the framework of the current physics, and that the establishment of a new physics is necessary for that ambitious purpose to be achieved.

Now we see instabilities, fluctuations, evolution onall levels of observations. This change of perspective requires newtools, new concepts. This volume invites the reader not to anenumeration of final achievements of contemporary science, but toan excursion to science in the making." --from the Foreword by I.Prigogine What are the dynamical roots of irreversibility? How can past andfuture be distinguished on the fundamental level of description?Are human beings the children of time --or its progenitors? Inrecent years, a growing number of chemists and physicists haveagreed that the solution to the problem of irreversibility requiresan extension of classical and quantum mechanics. There is, however,no consensus on which direction this extension should take toinclude the dynamical description of irreversible processes. Resonances, Instability, and Irreversibility surveys recentattempts --both direct and indirect --to address the problem ofirreversibility. Internationally recognized researchers report ontheir recent studies, which run the gamut from experimental tohighly mathematical. The subject matter of these papers falls intothree categories: classical systems with emphasis on chaos anddynamical instability, resonances and unstable quantum systems, andthe general problem of irreversibility. Presenting the cutting edge of research into some of the mostcompelling questions that face contemporary chemical physics,Resonances, Instability, and Irreversibility is fascinating readingfor professionals and students in every area of the discipline.

Download or read book Irreversibilities in Quantum Mechanics written by B. Fain and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of irreversibility is ubiquitous in physics and chemistry. The present book attempts to present a unified theoretical and conceptual framework for the description of various irreversible phenomena in quantum mechanics. In a sense, this book supplements conventional textbooks on quantum mechanics by including the theory of irreversibilities. However, the content and style of this book are more appropriate for a monograph than a textbook. We have tried to arrange the material so that, as far as possible, the reader need not continually refer elsewhere. The references to the literature make no pretense of completeness. The book is by no means a survey of present theoretical work. We have tried to highlight the basic principles and their results, while the attention has been mainly paid to the problems in which the author himself has been involved. The book as a whole is designed for the reader with knowledge of theoretical physics (especially quantum mechanics) at university level. This book is based on the courses of lectures given at the Chemistry Department of Tel-Aviv University.

Available in PDF, EPUB and Kindle. Book excerpt: The idea of editing the present volume in the Lecture Notes in Physics series arosewhileorganizingthe“ConferenceonIrreversibleQuantumDynamics”that took place at The Abdus Salam International Center for Theoretical Physics, Trieste, Italy, from July 29 to August 2, 2002. The aim of the Conference was to bring together di?erent groups of - searcherswhoseinterestsandpursuitsinvolveirreversibilityandtimeasymmetry in quantum mechanics. The Conference promoted open and in-depth exchanges of di?erent points of view, concerning both the content and character of qu- tum irreversibility and the methodologies used to study it. The following main themes were addressed: • Theoretical Aspects of Quantum Irreversible Dynamics • Open Quantum Systems and Applications • Foundational Aspects of Irreversible Quantum Dynamics • Asymmetric Time Evolution and Resonances Eachthemewasreviewedbyanexpertinthe?eld,accompaniedbymorespeci?c, research-like shorter talks. The whole topic of quantum irreversibility in all its manifold aspects has always raised a lot of interest, starting with the description of unstable systems in quantum mechanics and the issue of quantum measurement. Further, in - cent years a boost of activity concerning noise, dissipation and open systems has been prompted by the fast developing ?eld of quantum communication and information theory. These considerations motivated the editors to put together a volume that tries to summarize the present day status of the research in the ?eld, with the aim of providing the reader with an accessible and exhaustive introduction to it.

This book was released on 2011-10-06 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the book the idea of irreversibility as an inherent property of time is developed theoretically and experimentally. The matter is related with causality, and the method of causal analysis is presented. The quantum causal analysis helps understand the principle of week causality which admits extraction of information from the future without the classical paradoxes. It implies a possibility of observation of the future as the existing reality. So, the acceptance of time irreversibility leads to a striking manifestation of reversibility – signaling in reverse time. Quantum insight allows considering correlations of the distant irreversible processes as nonlocal ones originated from a macroscopic entanglement. The experimental approach to study of macroscopic nonlocality is discussed, and design of the experimental setup is described. The results of experiments on macroscopic nonlocal correlations, the signals in reverse time and their application to the forecast of large-scale random processes are expounded.

Download or read book Quantum Theory from a Nonlinear Perspective written by Dieter Schuch and published by Springer. This book was released on 2018-01-20 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a unique survey displaying the power of Riccati equations to describe reversible and irreversible processes in physics and, in particular, quantum physics. Quantum mechanics is supposedly linear, invariant under time-reversal, conserving energy and, in contrast to classical theories, essentially based on the use of complex quantities. However, on a macroscopic level, processes apparently obey nonlinear irreversible evolution equations and dissipate energy. The Riccati equation, a nonlinear equation that can be linearized, has the potential to link these two worlds when applied to complex quantities. The nonlinearity can provide information about the phase-amplitude correlations of the complex quantities that cannot be obtained from the linearized form. As revealed in this wide ranging treatment, Riccati equations can also be found in many diverse fields of physics from Bose-Einstein-condensates to cosmology. The book will appeal to graduate students and theoretical physicists interested in a consistent mathematical description of physical laws.

This book was released on 2013-06-29 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sitges International School of Physics is the second one to be held in Spain on the Many Body Problem. The first one took place on Mallorca during the summer 1969. The aim of the school was mainly to direct the interest of professors and students of Spanish Universities tow~rds this concrete field of re search. For this purpose 55 ~specially prepared lectures were given by an eminent collection of lecturers. Besides, a school of this class contri butes to the scientific formation of many students from other countries. Also, in a meeting of this kind, personal contacts are born that favour future co~laboration between scientists. In view of the success of the first two schools, we intend to foster future international meetings on this subject until interest in it is consolidated in Spain. All the lectures given are published here except those of Professor P.C. Martin whose lec tures have previously been published. I would like to thank all those people who helped to make this school a success, and in particular: Prof. J.L. Villar-Palasi, Minister of Educa tion of Spain for sponsoring the school. Dr. R. Diez-Hochleitner, Undersecretary of the Ministry of Education for receiving the project of this school with such enthusiasm. v PREFACE Prof. E.Costa-Novella, Director General of Universities in Spain and Dr. F.Arias-Salgado who showed such interest and patience while assuring the necessary finance would be found for the school.

This book was released on 1994-02-08 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Symposium on the Foundations of Modern Physics 1993 is the fourth in a series of conferences held in Joensuu, Finland, in the years 1985, 1987 and 1990 and is devoted to offering discussions on foundational problems of quantum mechanics and other fundamental physical theories, taking into account new experimental developments. The surveying of the progress with respect to fundamental questions of the quantum theory of measurement forms the guiding line of thought of the present Symposium, the main themes discussed being: the interrelation of quantum measurement and irreversibility; the physics of information (concerned with questions of information processing and quantum noise); quantum interference and mesoscopic quantum effects (searching for the micro-macro borderline); and the quantum-classical relationship (the need for classical pointer and their realisation).

This book was released on 2015-08-19 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to confusion with regard to exactly what entropy is, current scientific explanations of the associated irreversibility and the ineluctable increases in entropy are complicated, unsatisfactory, and completely incorrect. This problem is so impenetrable in fact that in over two centuries of notable attempts by the greatest scientific minds there has still been no explanation that is credible. The ubiquitous increases in entropy seem, however, to only affect the happenings at the macroscopic level of our everyday existence for which no process is completely reversible. Processes that are irreversible like those we witness every day with the naked eye are ipso facto those for which entropy is increased. But there has seemed to be no origin of this dire trend at the submicroscopic level where the answers to virtually all of the difficult problems of physics have been resolved. In resolving irreversibility at the submicroscopic level it has been necessary to augment Boltzmann's kinetic theory beyond two types of interaction and to more fully elaborate necessary constraints on the emission and absorption of radiation in Einstein's quantum theory of radiation. It is in the interactions between these domains where irreversibility enters. It has been incumbent upon us to close major loops left open by the scope of their analyses. Boltzmann could not have foreseen the impact of mediated interactions involving quantized photons, nor certainly relativistic effects. A comprehensive model has had to be developed to incorporate complimentary mechanical and radiational aspects of a thermodynamic system. The mediated interactions between molecules that do not involve direct collisions always reduce the relative velocity of the interacting molecules, which is very entropic behavior. In this way, individual submicroscopic processes 'use up' otherwise useful energy and increase entropy even at the submicroscopic level. Yet another form of interaction involving both radiational and particulate dynamics is the scattering of radiation by arrays of charges within a thermodynamic system. 'Forward' scattering in particular has traditionally been considered to involve conservative forces that do not alter the energetics of either the ensemble of particles or the radiation field. We show that this too is an over simplification whose correction has profound consequences of irreversible behavior, producing what have been considered 'cosmological' effects. The major loops that must be closed in this regard involve the origin of the ubiquitous hydrogenous intergalactic plasma with 24% helium by weight and the supposed disappearance of mass (and information) in black holes. There is increasing evidence that black holes do indeed errupt spewing forth hydrogenous plasma to again produce the 24% helium in generating the gamma radiation that after prolonged redshifting caused by irreversible scattering becomes the microwave background radiation. The blackbody temperature of a redshifting medium does not reflect the kinetic temperature of the particulate matter by which that radiation is scattered.

This book was released on 1995-08-31 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years nonlinear and irreversible quantum mechanics is becoming increasingly important because of the availability of precision experiments. There are new and successful attempts to understand quantum irreversibility. The development of generalized symmetries has to led to new families of evolution equations for pure and mixed states. On the one hand, this timely symposium covers nonlinear and irreversible quantum mechanics, the theory of quantization methods, causality and various problems important in this context. On the other hand, it reports the development of quantum group symmetries, and of methods to construct deformed quantum mechanical evolution equations like the q-deformed Schrödinger equations.

Book excerpt: The book focuses on the study of the temporal behavior of complex many-particle systems. The phenomenon of time and its role in the temporal evolution of complex systems is a remaining mystery. The book presents the necessity of the interdisciplinary point of view regarding on the phenomenon of time.The aim of the present study is to summarize and formulate in a concise but clear form the trends and approaches to the concept of time from a broad interdisciplinary perspective exposing tersely the complementary approaches and theories of time in the context of thermodynamics, statistical physics, cosmology, theory of information, biology and biophysics, including the problem of time and aging. Various approaches to the problem show that time is an extraordinarily interdisciplinary and multifaceted underlying notion which plays an extremely important role in various natural complex processes.

Download or read book The Emergent Multiverse written by David Wallace and published by OUP Oxford. This book was released on 2012-05-24 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Emergent Multiverse presents a striking new account of the 'many worlds' approach to quantum theory. The point of science, it is generally accepted, is to tell us how the world works and what it is like. But quantum theory seems to fail to do this: taken literally as a theory of the world, it seems to make crazy claims: particles are in two places at once; cats are alive and dead at the same time. So physicists and philosophers have often been led either to give up on the idea that quantum theory describes reality, or to modify or augment the theory. The Everett interpretation of quantum mechanics takes the apparent craziness seriously, and asks, 'what would it be like if particles really were in two places at once, if cats really were alive and dead at the same time'? The answer, it turns out, is that if the world were like that—if it were as quantum theory claims—it would be a world that, at the macroscopic level, was constantly branching into copies—hence the more sensationalist name for the Everett interpretation, the 'many worlds theory'. But really, the interpretation is not sensationalist at all: it simply takes quantum theory seriously, literally, as a description of the world. Once dismissed as absurd, it is now accepted by many physicists as the best way to make coherent sense of quantum theory. David Wallace offers a clear and up-to-date survey of work on the Everett interpretation in physics and in philosophy of science, and at the same time provides a self-contained and thoroughly modern account of it—an account which is accessible to readers who have previously studied quantum theory at undergraduate level, and which will shape the future direction of research by leading experts in the field.
