Quantum Leap by Vladimir G. Ivancevic Pdf

This is a unique 21st-century monograph that reveals a basic, yet deep understanding of the universe, as well as the human mind and body OCo all from the perspective of quantum mechanics and quantum field theory.This book starts with both non-mathematical and mathematical preliminaries. It presents the basics of both non-relativistic and relativistic quantum mechanics, and introduces Feynman path integrals and their application to quantum fields and string theory, as well as some non-quantum applications. It then describes the quantum universe in the form of loop quantum gravity and quantum cosmology. Lastly, the book turns to the human body and mind, applying quantum theory to electro-muscular stimulation and consciousness.It can be used as a graduate (or advanced undergraduate) textbook for a two-semester course in quantum physics and its modern applications. Some parts of the book can also be used by engineers, biologists, psychologists and computer scientists, as well as applied mathematicians, both in industry and academia."

Quantum Gravity by Claus Kiefer Pdf

The search for a quantum theory of the gravitational field is one of the great open problems in theoretical physics. This book presents a self-contained discussion of the concepts, methods and applications that can be expected in such a theory. The two main approaches to its construction — the direct quantisation of Einstein's general theory of relativity and string theory — are covered. Whereas the first attempts to construct a viable theory for the gravitational field alone, string theory assumes that a quantum theory of gravity will be achieved only through a unification of all the interactions. However, both employ the general method of quantization of constrained systems, which is described together with illustrative examples relevant for quantum gravity. There is a detailed presentation of the main approaches employed in quantum general relativity: path-integral quantization, the background-field method and canonical quantum gravity in the metric, connection and loop formulations. The discussion of string theory centres around its quantum-gravitational aspects and the comparison with quantum general relativity. Physical applications discussed at length include the quantization of black holes, quantum cosmology, the indications of a discrete structure of spacetime, and the origin of irreversibility. This third edition contains new chapters or sections on quantum gravity phenomenology, Horava-Lifshitz quantum gravity, analogue gravity, the holographic principle, and affine quantum gravity. It will present updates on loop quantum cosmology, the LTB model, asymptotic safety, and various discrete approaches. The third edition also contains pedagogical extensions throughout the text. This book will be of interest to researchers and students working in relativity and gravitation, cosmology, quantum field theory and related topics. It will also be of interest to mathematicians and philosophers of science.

Collective Classical And Quantum Fields: In Plasmas, Superconductors, Superfluid 3he, And Liquid Crystals by Hagen Kleinert Pdf

This is an introductory book dealing with collective phenomena in many-body systems. A gas of bosons or fermions can show oscillations of various types of density. These are described by different combinations of field variables. Especially delicate is the competition of these variables. In superfluid 3He, for example, the atoms can be attracted to each other by molecular forces, whereas they are repelled from each other at short distance due to a hardcore repulsion. The attraction gives rise to Cooper pairs, and the repulsion is overcome by paramagnon oscillations. The combination is what finally led to the discovery of superfluidity in 3He. In general, the competition between various channels can most efficiently be studied by means of a classical version of the Hubbard-Stratonovich transformation.A gas of electrons is controlled by the interplay of plasma oscillations and pair formation. In a system of rod- or disc-like molecules, liquid crystals are observed with directional orientations that behave in unusual five-fold or seven-fold symmetry patterns. The existence of such a symmetry was postulated in 1975 by the author and K Maki. An aluminium material of this type was later manufactured by Dan Shechtman which won him the 2014 Nobel prize. The last chapter presents some solvable models, one of which was the first to illustrate the existence of broken supersymmetry in nuclei.

Changing Paths by Bill Sherwonit Pdf

Changing Paths: Travels and Meditations in Alaska’s Arctic Wilderness is an autobiographical exploration of author Bill Sherwonit’s relationship with the Alaska wilderness. Written in three parts, it first describes Sherwonit’s introduction to the Brooks Range and his years as an exploration geologist. Taking a step back, the author then takes us into the past to explore his childhood roots in rural Connecticut and his recognition of wild nature as a refuge. He concludes with his emergence as a nature writer and wilderness advocate. An engrossing, fascinating, and eye-opening tale of one man’s life and of wilderness conceptions, this vivid description of an area of Alaska that few people get to experience is authentic and enlightening. It is an extraordinary contribution to the literature of place from one of Alaska’s most accomplished nature writers.

Changing Paths by Peter P. Houtzager,Michael Peter Moore Pdf

After two decades of marketizing, an array of national and international actors have become concerned with growing global inequality, the failure to reduce the numbers of very poor people in the world, and a perceived global backlash against international economic institutions. This new concern with poverty reduction and the political participation of excluded groups has set the stage for a new politics of inclusion within nations and in the international arena. The essays in this volume explore what forms the new politics of inclusion can take in low- and middle-income countries. The contributors favor a polity-centered approach that focuses on the political capacities of social and state actors to negotiate large-scale collective solutions and that highlights various possible strategies to lift large numbers of people out of poverty and political subordination. The contributors suggest there is little basis for the radical polycentrism that colors so much contemporary development thought. They focus on how the political capabilities of different societal and state actors develop over time and how their development is influenced by state action and a variety of institutional and other factors. The final chapter draws insightful conclusions about the political limitations and opportunities presented by current international discourse on poverty. Peter P. Houtzager is a Fellow at the Institute of Development Studies, University of Sussex. He has been a visiting scholar at the Center for Latin American Studies, University of California, Berkeley, visiting lecturer at Stanford University, and lecturer at St. Mary's College. A political scientist with broad training in comparative politics and historical-institutional analysis, he has written extensively on the institutional roots of collective action. Mick Moore is a Fellow at the Institute of Development Studies, University of Sussex, as well as Director of the Centre for the Future State. He has been a visiting professor at the Massachusetts Institute of Technology. His professional interests include political and institutional aspects of poverty reduction and of economic policy and performance, the politics and administration of development, and good government.

The Generation of Business Fluctuations by Corrado Di Guilmi Pdf

The limits imposed on economic modeling by the representative agent hypothesis have prevented dynamic analysis from fully exploring the links between the micro and macro level of the economic system. This book presents developments and applications of the innovative techniques of dynamic stochastic aggregation, first proposed by Masanao Aoki, through an implementation in a New Keynesian financial fragility framework. The introduction in macroeconomics of statistical mechanics tools, such as mean-field interaction, statistical entropy and master equation, constitutes a step toward a new definition of microfoundation and allows an integrated modeling of the relationships between micro financial variables and aggregate indicators.

Introduction to the Theory of Critical Phenomena by Dimo I Uzunov Pdf

This book provides a comprehensive introduction to the theory of phase transitions and critical phenomena. The content covers a period of more than 100 years of theoretical research of condensed matter phases and phase transitions providing a clear interrelationship with experimental problems. It starts from certain basic University knowledge of thermodynamics, statistical physics and quantum mechanics. The text is illustrated with classic examples of phase transitions. Various types of phase transition and (multi)critical points are introduced and explained. The classic aspects of the theory are naturally related with the modern developments. This interrelationship and the field-theoretical renormalization group method are presented in details. The main applications of the renormalization group methods are presented. Special attention is paid to the description of quantum phase transitions. This edition contains a more detailed presentation of the renormalization group method and its applications to particular systems.

Waves and Imaging Through Complex Media by P. Sebbah Pdf

Recent advances in wave propagation in random media are certainly consequences of new approaches to fundamental issues, as well as of a strong interest in potential applications. A collective effort has been made to present in this book the state of the art in fundamental concepts, as well as in biomedical imaging techniques. As an example, the recent introduction of wave chaos, and more specifically random matrix theory - an old tool from nuclear physics - to the study of multiple scattering, has pointed the way to a deeper understanding of wave coherence in complex media. At the same time, efficient new approaches for retrieving information from random media promise to allow wave imaging of small tumors in opaque tissues. Review chapters are written by experts in the field, with the aim of making the book accessible to the widest possible scientific audience: graduate students and research scientists in theoretical and applied physics, optics, acoustics, and biomedical physics.

Corotating Interaction Regions by A. Balogh,Jack Jokipii,R. Kallenbach,H. Kunow Pdf

This volume gives a comprehensive and integrated overview of current knowledge and understanding of corotating interaction regions (CIRs) in the solar wind. It is the result of a workshop at ISSI, where space scientists involved in the Ulysses, Pioneer, Voyager, IMP-8, Wind, and SOHO missions exchanged their data and interpretations with theorists in the fields of solar and heliospheric physics. The book provides a broad synthesis of current understanding of CIRs, which form at the interface between the fast solar wind originating in the northern and southern coronal holes and the slow solar wind that originates near and within coronal streamers surrounding the heliomagnetic equator. CIRs are the dominant structure in the heliosphere near and beyond Earth on the declining phase and near the minimum of the 11-year solar activity cycle. Particles energized at the shocks that bound CIRs at heliospheric distances beyond the orbit of Earth are the dominant energetic particle population observed in the outer heliosphere at these times. Papers included in this volume cover the subject of CIRs from their dissipation in the outer hemisphere, and include discussions of complexities associated with their evolution with distance from the Sun, their three-dimensional structure, and the myriad effects that CIRs have on energetic particles throughout the heliosphere. The book is intended to provide scientists active in space physics research with an up-to-date status report on current understanding of CIRs and their effects in the heliosphere, and also to serve the advanced graduate student with introductory material on this active field of research.
