Available in PDF, EPUB and Kindle. Book excerpt: This book collects lecture courses and seminars given at the Les Houches Summer School 2010 on "Quantum Theory: From Small to Large Scales". Fundamental quantum phenomena appear on all scales, from microscopic to macroscopic. Some of the pertinent questions include the onset of decoherence, the dynamics of collective modes, the influence of external randomness and the emergence of dissipative behaviour. Our understanding of such phenomena has been advanced by the study of model systems and by the derivation and analysis of effective dynamics for large systems and over long times. In this field, research in mathematical physics has regularly contributed results that were recognized as essential in the physics community. During the last few years, the key questions have been sharpened and progress on answering them has been particularly strong. This book reviews the state-of-the-art developments in this field and provides the necessary background for future studies. All chapters are written from a pedagogical perspective, making the book accessible to master and PhD students and researchers willing to enter this field.

Download or read book Quantum Space written by Jim Baggott and published by Oxford University Press, USA. This book was released on 2018-11-22 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behaviour of matter in a curved spacetime. This theory is the basis for the standard model of big bang cosmology. The discovery of gravitational waves at the LIGO observatory in the US (and then Virgo, in Italy) is only the most recent of this theory's many triumphs. The second is quantum mechanics. This theory describes the properties and behaviour of matter and radiation at their smallest scales. It is the basis for the standard model of particle physics, which builds up all the visible constituents of the universe out of collections of quarks, electrons and force-carrying particles such as photons. The discovery of the Higgs boson at CERN in Geneva is only the most recent of this theory's many triumphs. But, while they are both highly successful, these two structures leave a lot of important questions unanswered. They are also based on two different interpretations of space and time, and are therefore fundamentally incompatible. We have two descriptions but, as far as we know, we've only ever had one universe. What we need is a quantum theory of gravity. Approaches to formulating such a theory have primarily followed two paths. One leads to String Theory, which has for long been fashionable, and about which much has been written. But String Theory has become mired in problems. In this book, Jim Baggott describes "the road less travelled": an approach which takes relativity as its starting point, and leads to a structure called Loop Quantum Gravity. Baggott tells the story through the careers and pioneering work of two of the theory's most prominent contributors, Lee Smolin and Carlo Rovelli. Combining clear discussions of both quantum theory and general relativity, this book offers one of the first efforts to explain the new quantum theory of space and time.

Download or read book Quantum Physics For Beginners written by Jason Stephenson and published by Speedy Publishing LLC. This book was released on 2015-01-26 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: We may have lived knowing that the world around us operates in a way as if we observe them to be. This knowledge of how the universe operates, based primarily of our observations, has enabled us to predict actions and motions and allowed us to build machines and equipments that have made our lives easier and more enjoyable. The field that allowed us to do that is classical physics. The world, however, is advancing and our knowledge of how things are expands over time. We have discovered in the last few decades that these sets of rules that we have devised can perfectly describe the large-scale world but cannot accurately define the behaviors of particles in the microscopic world. This necessitated another field to explain the different behavior in the microscopic world: quantum physics.

Download or read book Quantum Mechanics Concepts and Applications written by Adaline Cerny and published by Murphy & Moore Publishing. This book was released on 2021-11-16 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum mechanics is a theory in physics that explains the physical properties of nature at the atomic and subatomic levels. It is fundamental to the study of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics defines many aspects of nature at an ordinary scale, while quantum mechanics describes the aspects of nature at small scales. Most theories in classical physics can be derived from quantum mechanics as an estimation valid at large scale. Quantum mechanics is used to describe observations which could not be resolved with classical physics. This book attempts to understand the multiple branches that fall under this discipline and how such concepts have practical applications. Different approaches, evaluations, methodologies and advanced studies on quantum mechanics have been included herein. The extensive content of this book provides the readers with a thorough understanding of the subject.

Download or read book The Large The Small And The Human Mind written by Roger Penrose and published by . This book was released on 1997 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Roger Penrose s original and provocative ideas about the large-scale physics of the Universe, the small-scale world of quantum physics and the physics of the mind have been the subject of controversy and discussion. These ideas were proposed in his best-selling books The Emperor s New Mind and Shadows of the Mind. In this book, he summarises and updates his current thinking in these complex areas to present a masterful summary of those areas of physics in which he feels there are major unresolved problems. Through this, he introduces radically new concepts which he believes will be fruitful in understanding the workings of the brain and the nature of the human mind. These ideas are challenged by three distinguished experts from different backgrounds: Abner Shimony and Nancy Cartwright as philosophers of science and Stephen Hawking as a theoretical physicist and cosmologist. Roger Penrose concludes with a response to their thought-provoking criticisms.

Download or read book Massively Small written by Stelios Pamfilis and published by Createspace Independent Publishing Platform. This book was released on 2016-06-01 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Massively Small takes you on a fascinating journey through cutting-edge science-from particle physics to astrophysics-unifying today's incompatible theories with a surprisingly simple idea from the dawn of science itself. For as long as human beings have had self-consciousness, we have wondered about the origins of the universe. Today, we use science to make sense of the world around us. Yet, despite the paradigm-shifting work of such pioneers as Isaac Newton, Max Plank, and Albert Einstein, among many others, modern theories such as photons, gravitons, motion, matter, space, and time all have major inconsistencies. Written for the general public, Massively Small identifies and articulates the anomalies plaguing the current physics. And by presenting new ideas in a novel framework-a framework drawn from ancient conceptualizations of the fundamental structure of reality-it boldly begins the process of shifting the paradigm yet again. From quantum mechanics to relativity, from theories of time, light, gravity, and mass to the cosmological theory of the big bang, this book shows how every question in physics can be answered by viewing the microstructures of the universe in a particular way. The ultimate goal is to reach a large-scale unified theory by beginning at the smallest scale.

Download or read book Probing Correlated Quantum Many Body Systems at the Single Particle Level written by Manuel Endres and published by Springer Science & Business. This book was released on 2014-04-26 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: How much knowledge can we gain about a physical system and to what degree can we control it? In quantum optical systems, such as ion traps or neutral atoms in cavities, single particles and their correlations can now be probed in a way that is fundamentally limited only by the laws of quantum mechanics. In contrast, quantum many-body systems pose entirely new challenges due to the enormous number of microscopic parameters and their small length- and short time-scales. This thesis describes a new approach to probing quantum many-body systems at the level of individual particles: Using high-resolution, single-particle-resolved imaging and manipulation of strongly correlated atoms, single atoms can be detected and manipulated due to the large length and time-scales and the precise control of internal degrees of freedom. Such techniques lay stepping stones for the experimental exploration of new quantum many-body phenomena and applications thereof, such as quantum simulation and quantum information, through the design of systems at the microscopic scale and the measurement of previously inaccessible observables.

Download or read book Complexity from Microscopic to Macroscopic Scales Coherence and Large Deviations written by A.T. Skjeltorp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many mesoscopic systems display `adaptive' behaviour - changes in some physical property that results from a small change in an internal or external driving force. There is a kind of progression in adaptive phenomena, from quantum mesoscopics to complex, evolved cooperative systems and large scale events like turbulence. The field of mesoscopic magnetism, especially quantum coherence and quantum tunnelling in spin systems, and the coupling between mesoscopic magnetism and mesoscopic transport is currently a very active area of solid state physics. `Dephasing' is an important concept in mesoscopic systems like these. A basic question is the limit at which quantum mechanics breaks down and what it can be replaced with. Another interesting crossover is that between complexity and large excursions or events, with turbulence as a prototype example. The book also contains a discussion of finance. Qualitatively speaking, turbulence and financial markets are apparently similar, so our understanding of turbulence may be relevant to understanding price fluctuations.

Download or read book Nonlocal Quantum Field Theory and Stochastic Quantum Mechanics written by K.H. Namsrai and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: over this stochastic space-time leads to the non local fields considered by G. V. Efimov. In other words, stochasticity of space-time (after being averaged on a large scale) as a self-memory makes the theory nonlocal. This allows one to consider in a unified way the effect of stochasticity (or nonlocality) in all physical processes. Moreover, the universal character of this hypothesis of space-time at small distances enables us to re-interpret the dynamics of stochastic particles and to study some important problems of the theory of stochastic processes [such as the relativistic description of diffusion, Feynman type processes, and the problem of the origin of self-turbulence in the motion of free particles within nonlinear (stochastic) mechanics]. In this direction our approach (Part II) may be useful in recent developments of the stochastic interpretation of quantum mechanics and fields due to E. Nelson, D. Kershaw, I. Fenyes, F. Guerra, de la Pena-Auerbach, J. -P. Vigier, M. Davidson, and others. In particular, as shown by N. Cufaro Petroni and J. -P. Vigier, within the discussed approach, a causal action-at-distance interpretation of a series of experiments by A. Aspect and his co-workers indicating a possible non locality property of quantum mechanics, may also be obtained. Aspect's results have recently inspired a great interest in different nonlocal theories and models devoted to an understanding of the implications of this nonlocality. This book consists of two parts.

Download or read book Quantum Enigma written by Bruce Rosenblum and published by Oxford University Press. This book was released on 2011-08-01 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: In trying to understand the atom, physicists built quantum mechanics, the most successful theory in science and the basis of one-third of our economy. They found, to their embarrassment, that with their theory, physics encounters consciousness. Authors Bruce Rosenblum and Fred Kuttner explain all this in non-technical terms with help from some fanciful stories and anecdotes about the theory's developers. They present the quantum mystery honestly, emphasizing what is and what is not speculation. Quantum Enigma's description of the experimental quantum facts, and the quantum theory explaining them, is undisputed. Interpreting what it all means, however, is heatedly controversial. But every interpretation of quantum physics involves consciousness. Rosenblum and Kuttner therefore turn to exploring consciousness itself--and encounter quantum mechanics. Free will and anthropic principles become crucial issues, and the connection of consciousness with the cosmos suggested by some leading quantum cosmologists is mind-blowing. Readers are brought to a boundary where the particular expertise of physicists is no longer the only sure guide. They will find, instead, the facts and hints provided by quantum mechanics and the ability to speculate for themselves. In the few decades since the Bell's theorem experiments established the existence of entanglement (Einstein's "spooky action"), interest in the foundations, and the mysteries, of quantum mechanics has accelerated. In recent years, physicists, philosophers, computer engineers, and even biologists have expanded our realization of the significance of quantum phenomena. This second edition includes such advances. The authors have also drawn on many responses from readers and instructors to improve the clarity of the book's explanations.

Download or read book A New Approach to Quantum Gravity written by Balungi Francis and published by Bill Stone Services. This book was released on 2018-06-27 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Standard Model is inconsistent with that of general relativity, to the point that one or both theories break down under certain conditions (for example within known space time singularities like the Big Bang and the centers of black holes beyond the event horizon). The appearance of singularities in any physical theory is an indication that something is wrong and that there is a need for new physics. Singularities can be avoided in GR and any field theory through the introduction of an efficient regularization procedure as this book directs. Regularization is a method of modifying observables which have singularities in order to make them finite by the introduction of a suitable parameter called regulator. The regulator, also known as a "cutoff", models our lack of knowledge about physics at unobserved scales (e.g. scales of small size or large energy levels). It compensates for the possibility that "new physics" (beyond the SM) may be discovered at those scales which the present theory is unable to model, while enabling the current theory to give accurate predictions as an "effective theory" within its intended scale of use. Therefore the main objective of this book is to discover new physics (Quantum Gravity) at those scales (or extra dimensions) which the General relativity theory and Quantum mechanics is unable to model. This has been achieved and remains the work of an experimenter to verify. While this is a new approach to quantum gravity, it reproduces the results in loop quantum gravity and string theory as the book indicates. This book provides a complete overview of quantum gravity from the frontiers of theoretical physics research for graduate students and researchers.

Download or read book Lost in Math written by Sabine Hossenfelder and published by Basic Books. This book was released on 2018-06-12 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this "provocative" book (New York Times), a contrarian physicist argues that her field's modern obsession with beauty has given us wonderful math but bad science. Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria. Worse, these "too good to not be true" theories are actually untestable and they have left the field in a cul-de-sac. To escape, physicists must rethink their methods. Only by embracing reality as it is can science discover the truth.
