Download or read book Origin of Symmetries written by C. D. Froggatt and published by World Scientific. This book was released on 1991 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development in our understanding of symmetry principles is reviewed. Many symmetries, such as charge conjugation, parity and strangeness, are no longer considered as fundamental but as natural consequences of a gauge field theory of strong and electromagnetic interactions. Other symmetries arise naturally from physical models in some limiting situation, such as for low energy or low mass. Random dynamics and attempts to explain all symmetries ? even Lorentz invariance and gauge invariance ? without appealing to any fundamental invariance of the laws of nature are discussed. A selection of original papers is reprinted.

Download or read book Making 20th Century Science written by Stephen G. Brush and published by Oxford University Press. This book was released on 2015-03-16 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, the scientific method has been said to require proposing a theory, making a prediction of something not already known, testing the prediction, and giving up the theory (or substantially changing it) if it fails the test. A theory that leads to several successful predictions is more likely to be accepted than one that only explains what is already known but not understood. This process is widely treated as the conventional method of achieving scientific progress, and was used throughout the twentieth century as the standard route to discovery and experimentation. But does science really work this way? In Making 20th Century Science, Stephen G. Brush discusses this question, as it relates to the development of science throughout the last century. Answering this question requires both a philosophically and historically scientific approach, and Brush blends the two in order to take a close look at how scientific methodology has developed. Several cases from the history of modern physical and biological science are examined, including Mendeleev's Periodic Law, Kekule's structure for benzene, the light-quantum hypothesis, quantum mechanics, chromosome theory, and natural selection. In general it is found that theories are accepted for a combination of successful predictions and better explanations of old facts. Making 20th Century Science is a large-scale historical look at the implementation of the scientific method, and how scientific theories come to be accepted.

Download or read book Quantum Hall Effects Field Theoretical Approach And Related Topics 2nd Edition written by Zyun Francis Ezawa and published by World Scientific Publishing Company. This book was released on 2008-01-21 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quantum Hall effect (QHE) is one of the most fascinating and beautiful phenomena in all branches of physics. Tremendous theoretical and experimental developments are still being made in this sphere. In the original edition of this book, composite bosons, composite fermions and fractional charged excitations (anyons) were among the distinguished ideas presented. This new edition includes many novel ideas according to recent progress. Fantastic phenomena associated with the interlayer phase coherence and SU(4) quantum Hall ferromagnets in the bilayer system are extensively reviewed. The microscopic theory of the QHE is formulated based on noncommutative geometry, the underlying mathematical structure. Quasiparticles are described as noncommutative solitons. The coverage also includes the recent development of the unconventional QHE in graphene (a single atomic layer graphite), where the electron dynamics can be treated as relativistic Dirac fermions and even the supersymmetric quantum mechanics plays a key role. An instructive and comprehensive overview of the QHE, this book is also suitable as an introduction to quantum field theory with vivid applications. Only a knowledge of quantum mechanics is assumed.

Download or read book The Theory of Beta Decay written by C. Strachan and published by Elsevier. This book was released on 2016-07-29 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Theory of Beta-Decay covers the formulas, theories, probabilities, and spectra of beta-decay. This book is divided into 2 parts compassing 12 chapters, and starts with the introduction to the neutrino and the quantum theoretical background, explaining the basic phenomenon of beta-decay and the emission of electrons. The subsequent chapters deal with the interaction and the transition probability, as well as formulas of solutions. These topics are followed by discussions on the developments in the non-conservation of parity and helicity, the two-component theory of the neutrino, possible invariance under time-reversal and charge conjugation, leptonic number of lepton charge, and muon decay and other theories. Other chapters describe the tentative theory of beta-radiation, the detection of the free neutrino, and the selection rules for the beta-disintegration. The last chapters consider questions and experimental test about beta-decay. The chapters also look into the theories and helicity of neutrino, the theory of the Fermi interaction, and the test of the nature of the vector interaction in beta-decay This book will be of value to physicists and researchers in the allied fields.

Download or read book Symmetries and Symmetry Breaking in Field Theory written by Parthasarathi Mitra and published by CRC Press. This book was released on 2014-05-14 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many courses on modern quantum field theory focus on the formulation and application of field theory, leaving topics related to symmetry underdeveloped. This leads to students often having an incomplete understanding of symmetries. Filling this gap, Symmetries and Symmetry Breaking in Field Theory sheds light on various aspects of symmetry in field theory. The book presents a broad selection of important topics, including constraint theory, generalized Pauli–Villars regularization, the measure approach to anomalies, zeta function regularization, and anomalous gauge theories. The author explains how some classical symmetries are broken by anomalies and how other symmetries of the theory are spontaneously broken. He discusses all of the ideas in as simple a way as possible.

Download or read book Quark Gluon Plasma Theoretical Foundations written by J. Kapusta and published by Gulf Professional Publishing. This book was released on 2003-11-25 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this volume is to trace the development of the theoretical understanding of quark-gluon plasma, both in terms of the equation of state and thermal correlation functions and in terms of its manifestation in high energy nuclear collisions. Who among us has not wondered how tall a mountain is on a neutron star, what happens when matter is heated and compressed to higher and higher densities, what happens when an object falls into a black hole, or what happened eons ago in the early universe? The study of quark-gluon plasma is related in one way or another to these and other thought provoking questions. Oftentimes the most eloquent exposition is given in the original papers. To this end a selection is made of what are the most important pioneering papers in this field. The early 1950s was an era when high energy multiparticle production in cosmic ray interactions attracted the attention of some of the brightest minds in physics, and so it should be no surprise that the first reprinted papers deal with the introduction of statistical models of particle production. The quark model arose in the 1960s, while QCD as such was recognized as the theory of the strong interactions in the 1970's. The behavior of matter at high temperatures and supranuclear densities became of wide interest in the nuclear and particle physics communities starting in the 1970s, which is when the concept of quark-gluon plasma became established. The history of the field has been traced up to the early 1990s. There are three reasons for stopping at that point in time. First, most of the key theoretical concepts and formalisms arose before 1993, although many of them continue to be developed today and hopefully well into the future. Second, papers written after 1992 are much more readily available than those writen before due to the advent of the World Wide Web and its electronic preprint databases and journals. Finally, in making this collection of reprints available as hardcopy one is limited in the number of pages, and some papers in the present selection should have been deleted in order to make room for post-1993 papers. For the same reason the subject focus must of necessity be limited, which means that in this reprint collection two wide subject areas are not addressed: the behavior of nuclear matter under extreme conditions is not reported, nor is quark matter in neutron stars. The broad categories into which the material has been placed, reflect the diverse studies of quark-gluon plasma and its manifestation. They are: phase-space models of particle production, perturbative QCD plasma, lattice gauge theory, fluid dynamics and flow, strangeness, heavy flavor (charm), electromagnetic signals, parton cascade and minijets, parton energy loss and jet quenching, Hanbury Brown--Twiss (HBT) interferometry, disoriented chiral condensates, phase transition dynamics and cosmology, and color superconductivity. Each chapter is prefaced by an introduction, which contains a list of significant papers which is more complete than the reprinted papers, though by no means exhaustive. It also contains citations to most relevant papers published up to the date of completion of this volume (fall 2002). It is hoped that the short reviews will help bring the reader up to date on the latest developments. The selection of papers cited in each chapter, and in particular the ones selected for reprinting, is solely the responsibility of the Editors. It is based on their best judgement and experience in this field dating back to the mid-1970s. In order to be reprinted a paper must have been pioneering in the sense of originality and impact on the field. Generally they have been cited over a hundred times by other papers published in refereed journals. The final selection was reviewed and discussed among the Editors repeatedly. Just because a paper is not included does not mean they do not know of it or do not have a high regard for it. All of the papers cited or reprinted are original research contributions. There are three other types of publications listed. The first is a compilation of books. The second is a list of reviews, many of which contain a significant amount of original material. The third is a list of the proceedings of the series of Quark Matter meetings, the primary series of international conferences in this field that is attended by both theorists and experimentalists.

Download or read book Thermal aspects of field theories written by Adailton Azevêdo Araújo Filho and published by Amazon.com. This book was released on 2022-06-30 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focus on examining the thermodynamic properties of various prominent field theories concerning high-energy and condensed matter physics. We make the usage of the theory of ensembles to perform our analysis. At the beginning, we supply the thermodynamic properties based on the formalism of canonical ensemble to the Aharonov-Bohm quantum ring considering both scenarios: the relativistic and the non-relativistic cases. Next, we construct a model in order to study quantum gases. In this context, we examine bosons, fermions and spinless particles within the grand-canonical ensemble taking into account two different approaches: interacting and noninteracting particles. To corroborate our results, we apply them to the Bose-Einstein condensate and to the helium dimmers. The same approach is applied considering rather Lorentz violation. Moreover, in this context, we also propose two applications to support our theoretical calculations: phosphorene layers and spin precession of quantum gases. Next, the thermodynamic properties are investigated as well to a variety of models/theories (regarding different energy dispersion relations) when the Lorentz symmetry is no longer maintained within the canonical ensemble formalism. To these cases, three distinct thermal scenarios of the universe are considered: the cosmic microwave background, the electroweak epoch, and the inflationary period.

Download or read book Strange Beauty written by George Johnson and published by Vintage. This book was released on 2010-09-29 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a New Afterword "Our knowledge of fundamental physics contains not one fruitful idea that does not carry the name of Murray Gell-Mann."--Richard Feynman Acclaimed science writer George Johnson brings his formidable reporting skills to the first biography of Nobel Prize-winner Murray Gell-Mann, the brilliant, irascible man who revolutionized modern particle physics with his models of the quark and the Eightfold Way. Born into a Jewish immigrant family on New York's East 14th Street, Gell-Mann's prodigious talent was evident from an early age--he entered Yale at 15, completed his Ph.D. at 21, and was soon identifying the structures of the world's smallest components and illuminating the elegant symmetries of the universe. Beautifully balanced in its portrayal of an extraordinary and difficult man, interpreting the concepts of advanced physics with scrupulous clarity and simplicity, Strange Beauty is a tour-de-force of both science writing and biography.

Download or read book Golden Age Of Theoretical Physics The Boxed Set Of 2 Vols written by Jagdish Mehra and published by World Scientific. This book was released on 2001-02-28 with total page 1436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Golden Age of Theoretical Physics brings together 37 selected essays. Many of these essays were first presented as lectures at various universities in Europe and the USA, and then published as reports or articles. Their enlarged, final versions were published in the joint work of Jagdish Mehra and Helmut Rechenberg, The Historical Development of Quantum Theory, while the other essays were published as articles in scientific journals or in edited books. Here they are published together as a tribute to the Mehra-Rechenberg collaboration sustained for several decades, and cover various aspects of quantum theory, the special and general theories of relativity, the foundations of statistical mechanics, and some of their fundamental applications. Two essays, ‘Albert Einstein's “First” Paper’ (Essay 1) and ‘The Dream of Leonardo da Vinci’ (Essay 37), lie outside the major themes treated in this book, but are included here because of their historical interest. The origin of each essay is explained in a footnote.This book deals with the most important themes developed in the first 40 years of the twentieth century by some of the greatest pioneers and architects of modern physics. It is a vital source of information about what can veritably be described as ‘the golden age of theoretical physics’.
