Download or read book Supersymmetry In The Theories Of Fields Strings Branes Procs Of The Advanced School written by Jose L Fernandez Barbon and published by World Scientific. This book was released on 2000-12-18 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last three decades supersymmetry has grown into one of the busiest theoretical avenues of particle physics. Supersymmetric ideas dominate the scenario of “beyond the standard model phenomenology”, in spite of the thirty-year-old experimental opacity, a situation that could change within the following decade. One additional important reason for the good health of supersymmetry must be found in the most speculative areas of particle physics. Much of its success comes from superstring theory.The Advanced School on Supersymmetry in the Theories of Fields, Strings and Branes attempted to provide an up-to-date perspective of the role played by supersymmetry in these subjects. The lectures dealt with most of the main theoretical developments of the nineties, from the exact solutions of the Seiberg-Witten type to the physics of D-branes and their impact on the physics of black holes and string phenomenology. Many of these results are contrasted with the recent results on the holographic duality between string theories in anti-de Sitter spaces and certain large N conformal gauge theories, the so-called “Maldacena conjecture”, or “AdS/CFT correspondence”. The lecture notes contained in this volume are the result of the effort made by the lecturers to introduce the reader to these topics, assuming a basic knowledge of supersymmetry, quantum field theory and string theory.

Download or read book Eighth Marcel Grossmann Meeting The On Recent Developments In Theoretical And Experimental General Relativity Gravitation And Relativistic Field Theories Proceedings Of The Meeting In 2 Parts written by Tsvi Piran and published by World Scientific. This book was released on 1999-05-14 with total page 1776 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1975, the Marcel Grossmann Meetings have been organized to provide opportunities for discussing recent advances in gravitation, general relativity and relativistic field theories, emphasizing mathematical foundations, physical predictions and experimental tests. The objective of these meetings is to facilitate exchange among scientists that may deepen our understanding of space-time structures and to review the status of ongoing experiments aimed at testing Einstein's theory of gravitation from either the ground or space.The Eighth Marcel Grossmann Meeting took place on 22-27 June, 1997, at the Hebrew University of Jerusalem, Israel. The scientific program included 25 plenary talks and 40 parallel sessions during which 400 papers were presented. The papers that appear in this book cover all aspects of gravitation, from mathematical issues to recent observations and experiments.
Download or read book Effective Spacetime written by Karen Crowther and published by Springer. This book was released on 2016-07-07 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the notion that quantum gravity may represent the "breakdown" of spacetime at extremely high energy scales. If spacetime does not exist at the fundamental level, then it has to be considered "emergent", in other words an effective structure, valid at low energy scales. The author develops a conception of emergence appropriate to effective theories in physics, and shows how it applies (or could apply) in various approaches to quantum gravity, including condensed matter approaches, discrete approaches, and loop quantum gravity.
Download or read book Quantum Field Theory II written by Edouard B. Manoukian and published by Springer. This book was released on 2016-09-26 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book takes a pedagogical approach to explaining quantum gravity, supersymmetry and string theory in a coherent way. It is aimed at graduate students and researchers in quantum field theory and high-energy physics. The first part of the book introduces quantum gravity, without requiring previous knowledge of general relativity (GR). The necessary geometrical aspects are derived afresh leading to explicit general Lagrangians for gravity, including that of general relativity. The quantum aspect of gravitation, as described by the graviton, is introduced and perturbative quantum GR is discussed. The Schwinger-DeWitt formalism is developed to compute the one-loop contribution to the theory and renormalizability aspects of the perturbative theory are also discussed. This follows by introducing only the very basics of a non-perturbative, background-independent, formulation of quantum gravity, referred to as “loop quantum gravity”, which gives rise to a quantization of space. In the second part the author introduces supersymmetry and its consequences. The generation of superfields is represented in detail. Supersymmetric generalizations of Maxwell’s Theory as well as of Yang-Mills field theory, and of the standard model are worked out. Spontaneous symmetry breaking, improvement of the divergence problem in supersymmetric field theory, and its role in the hierarchy problem are covered. The unification of the fundamental constants in a supersymmetric version of the standard model are then studied. Geometrical aspects necessary to study supergravity are developed culminating in the derivation of its full action. The third part introduces string theory and the analysis of the spectra of the mass (squared) operator associated with the oscillating strings. The properties of the underlying fields, associated with massless particles, encountered in string theory are studied in some detail. Elements of compactification, duality and D-branes are given, as well of the generation of vertices and interactions of strings. In the final sections, the author shows how to recover GR and the Yang-Mills field Theory from string theory.
Download or read book Quantum Field Theory I written by Edouard B. Manoukian and published by Springer. This book was released on 2016-12-01 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook covers a broad spectrum of developments in QFT, emphasizing those aspects that are now well consolidated and for which satisfactory theoretical descriptions have been provided. The book is unique in that it offers a new approach to the subject and explores many topics merely touched upon, if covered at all, in standard reference works. A detailed and largely non-technical introductory chapter traces the development of QFT from its inception in 1926. The elegant functional differential approach put forward by Schwinger, referred to as the quantum dynamical (action) principle, and its underlying theory are used systematically in order to generate the so-called vacuum-to-vacuum transition amplitude of both abelian and non-abelian gauge theories, in addition to Feynman’s well-known functional integral approach, referred to as the path-integral approach. Given the wealth of information also to be found in the abelian case, equal importance is put on both abelian and non-abelian gauge theories. Particular emphasis is placed on the concept of a quantum field and its particle content to provide an appropriate description of physical processes at high energies, where relativity becomes indispensable. Moreover, quantum mechanics implies that a wave function renormalization arises in the QFT field independent of any perturbation theory - a point not sufficiently emphasized in the literature. The book provides an overview of all the fields encountered in present high-energy physics, together with the details of the underlying derivations. Further, it presents “deep inelastic” experiments as a fundamental application of quantum chromodynamics. Though the author makes a point of deriving points in detail, the book still requires good background knowledge of quantum mechanics, including the Dirac Theory, as well as elements of the Klein-Gordon equation. The present volume sets the language, the notation and provides additional background for reading Quantum Field Theory II - Introduction to Quantum Gravity, Supersymmetry and String Theory, by the same author. Students in this field might benefit from first reading the book Quantum Theory: A Wide Spectrum (Springer, 2006), by the same author.
Download or read book Our Common Cosmos written by Zoë Lehmann Imfeld and published by Bloomsbury Publishing. This book was released on 2018-12-27 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume collects an international body of voices, as a timely response to a rapidly advancing field of the natural sciences. The contributors explore how the disciplines of theology, earth and space sciences contribute to the debate on constantly expanding ethical challenges, and the prospect of humanity's future. The discussions offered in this volume see the 'community' as central to a sustainable and ethical approach to earth and space sciences, examining the role of theology in this communal approach, but also recognizing theology itself as part of a community of humanity disciplines. Examining the necessity for interaction between disciplines, this collection draws on voices from biodiversity studies, geology, aesthetics, literature, astrophysics, and others, to illustrate precisely why a constructive and sustainable dialogue is needed within the current scientific climate.

Download or read book Memorial Volume For Y Nambu written by Lars Brink and published by World Scientific. This book was released on 2016-05-20 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have lost one of the giants of the twentieth century physics when Yoichiro Nambu passed away in July, 2015, at the age of 94.Today's Standard Model, though still incomplete in many respects, is the culmination of the most successful theory of the Universe to date, and it is built upon foundations provided by discoveries made by Nambu in the 1960s: the mechanism of spontaneously broken symmetry in Nature (with G Jona-Lasinio) and the hidden new SU(3) symmetry of quarks and gluons (with M-Y Han).In this volume honoring Nambu's memory, World Scientific Publishing presents a unique collection of papers written by his former colleagues, collaborating researchers and former students and associates, not only citing Nambu's great contributions in physics but also many personal and private reminiscences, some never told before. This volume also contains the very last scientific writing by Professor Nambu himself, discussing the development of particle physics.This book is a volume for all who benefited not only from Nambu's contributions toward understanding the Universe but also his warm and kind persona. It is a great addition to the history of contemporary physics.
Download or read book Educational Effectiveness Theory written by Katharina Maag Merki and published by Routledge. This book was released on 2018-10-11 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the advances in educational effectiveness theory and methodology in the last 20 years, important questions and issues remain unresolved. In particular, existing theoretical frameworks of educational effectiveness are only able to describe the interrelationship among factors at the system, school, classroom, and student levels and their cross-level interdependency in a very general manner. Additionally, although a large number of studies provide empirical evidence of the impact of single factors and factor constellations on student learning, the embedding of the empirically identified results in theoretical models of educational effectiveness has to be carried out more systematically in order to develop more elaborated theories of educational effectiveness. The aim of this book is to contribute to the advancement of educational effectiveness theory by discussing different strategies: including alternative theoretical models to understand educational in/effectiveness, extending the methodology to analyze processes and mechanisms of educational in/effectiveness, analyzing differential effects of processes and instruments on educational in/effectiveness, carrying out complex multivariate analyses considering manifest and latent variables, and combining theory and practice in real school situations. Taken together, the strategies presented in this book make it clear that the advancement of educational effectiveness theory depends on the advancement of educational effectiveness methodology, or in other words: from theory to methodology and from empirical evidence back to theory. This book was originally published as a special issue of School Effectiveness and School Improvement.

Download or read book Quantum Gravity and the Functional Renormalization Group written by Martin Reuter and published by Cambridge University Press. This book was released on 2019-01-03 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past two decades the gravitational asymptotic safety scenario has undergone a major transition from an exotic possibility to a serious contender for a realistic theory of quantum gravity. It aims at a mathematically consistent quantum description of the gravitational interaction and the geometry of spacetime within the realm of quantum field theory, which keeps its predictive power at the highest energies. This volume provides a self-contained pedagogical introduction to asymptotic safety, and introduces the functional renormalization group techniques used in its investigation, along with the requisite computational techniques. The foundational chapters are followed by an accessible summary of the results obtained so far. It is the first detailed exposition of asymptotic safety, providing a unique introduction to quantum gravity and it assumes no previous familiarity with the renormalization group. It serves as an important resource for both practising researchers and graduate students entering this maturing field.
Download or read book The Foundation of Reality written by David Glick and published by Oxford University Press. This book was released on 2020-04-29 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Are space and time fundamental features of our world or might they emerge from something else? The Foundation of Reality brings together metaphysicians and philosophers of physics working on space, time, and fundamentality to address this timely question. Recent developments in the interpretation of quantum mechanics and the understanding of certain approaches to quantum gravity have led philosophers of physics to propose that space and time might be emergent rather than fundamental. But such discussions are often conducted without engagement with those working on fundamentality and related issues in contemporary metaphysics. This book aims to correct this oversight. The diverse contributions to this volume address topics including the nature of fundamentality, the relation of space and time to quantum entanglement, and space and time in theories of quantum gravity. Only through consideration of a range of different approaches to the topic can we hope to get clear on the status of space and time in our contemporary understanding of physical reality.
Download or read book Physics of the Human Mind written by Ihor Lubashevsky and published by Springer. This book was released on 2017-02-12 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tackles the challenging question which mathematical formalisms and possibly new physical notions should be developed for quantitatively describing human cognition and behavior, in addition to the ones already developed in the physical and cognitive sciences. Indeed, physics is widely used in modeling social systems, where, in particular, new branches of science such as sociophysics and econophysics have arisen. However, many if not most characteristic features of humans like willingness, emotions, memory, future prediction, and moral norms, to name but a few, are not yet properly reflected in the paradigms of physical thought and theory. The choice of a relevant formalism for modeling mental phenomena requires the comprehension of the general philosophical questions related to the mind-body problem. Plausible answers to these questions are investigated and reviewed, notions and concepts to be used or to be taken into account are developed and some challenging questions are posed as open problems. This text addresses theoretical physicists and neuroscientists modeling any systems and processes where human factors play a crucial role, philosophers interested in applying philosophical concepts to the construction of mathematical models, and the mathematically oriented psychologists and sociologists, whose research is fundamentally related to modeling mental processes.
