Band-Ferromagnetism: Ground-State and Finite-Temperature Phenomena (Lecture Notes in Physics #580)

by K. Baberschke M. Donath W. Nolting

The fascinating phenomenon ferromagnetism is far from being fully understood, although it surely belongs to the oldest problems of solid state physics. For any investigation it appears recommendable to distinguish between materials whose spontaneous magnetization stems from localized electrons of a partially ?lled atomic shell and those in which it is due to itinerant electrons of a partially ?lled conduction band. In the latter case one speaks of band-ferromagnetism, prototypes of which are the classical ferromagnets Fe, Co, and Ni. The present book is a status report on the remarkable progress that has recently been made towards a microscopic understanding of band-ferromagnetism as an electron c- relation e?ect. The authors of the various chapters of this book “Band-Ferromagnetism: Ground-State and Finite-Temperature Phenomena” participated as selected - perts in the 242nd WE-Heraeus-Seminar (4-6 October 2000) held under almost the same title in Wandlitz near Berlin (Germany). It was the second seminar of this type in Wandlitz. (The ?rst in 1998 dealt with the complementary topic of the physics of local-moment ferromagnets such as Gd). Twenty-six invited spe- ers from ten di?erent countries together with ?fty-?ve further participants, who presented contributions in form of posters, spent three days together discussing in an enthusiastic and fertile manner the hot topics of band-ferromagnetism.

Partial Differential Equations V: Asymptotic Methods for Partial Differential Equations (Encyclopaedia of Mathematical Sciences #34)

by V. M. Babich N. S. Bakhvalov M. V. Fedoryuk A. M. Il'In V. F. Lazutkin G. Panasenko A. L. Shtaras B. R. Vainberg

In this paper we shall discuss the construction of formal short-wave asymp­ totic solutions of problems of mathematical physics. The topic is very broad. It can somewhat conveniently be divided into three parts: 1. Finding the short-wave asymptotics of a rather narrow class of problems, which admit a solution in an explicit form, via formulas that represent this solution. 2. Finding formal asymptotic solutions of equations that describe wave processes by basing them on some ansatz or other. We explain what 2 means. Giving an ansatz is knowing how to give a formula for the desired asymptotic solution in the form of a series or some expression containing a series, where the analytic nature of the terms of these series is indicated up to functions and coefficients that are undetermined at the first stage of consideration. The second stage is to determine these functions and coefficients using a direct substitution of the ansatz in the equation, the boundary conditions and the initial conditions. Sometimes it is necessary to use different ansiitze in different domains, and in the overlapping parts of these domains the formal asymptotic solutions must be asymptotically equivalent (the method of matched asymptotic expansions). The basis for success in the search for formal asymptotic solutions is a suitable choice of ansiitze. The study of the asymptotics of explicit solutions of special model problems allows us to "surmise" what the correct ansiitze are for the general solution.

Neoclassical Theory of Electromagnetic Interactions: A Single Theory for Macroscopic and Microscopic Scales (Theoretical and Mathematical Physics)

by Anatoli Babin Alexander Figotin

In this monograph, the authors present their recently developed theory of electromagnetic interactions. This neoclassical approach extends the classical electromagnetic theory down to atomic scales and allows the explanation of various non-classical phenomena in the same framework.While the classical Maxwell–Lorentz electromagnetism theory succeeds in describing the physical reality at macroscopic scales, it struggles at atomic scales. Here, quantum mechanics traditionally takes over to describe non-classical phenomena such as the hydrogen spectrum and de Broglie waves. By means of modifying the classical theory, the approach presented here is able to consistently explain quantum-mechanical effects, and while similar to quantum mechanics in some respects, this neoclassical theory also differs markedly from it. In particular, the newly developed framework omits probabilistic interpretations of the wave function and features a new fundamental spatial scale which, at the size of the free electron, is much larger than the classical electron radius and is relevant to plasmonics and emission physics.This book will appeal to researchers interested in advanced aspects of electromagnetic theory. Treating the classical approach in detail, including non-relativistic aspects and the Lagrangian framework, and comparing the neoclassical theory with quantum mechanics and the de Broglie–Bohm theory, this work is completely self-contained.

Self-Organization, Emerging Properties, and Learning (Nato Science Series B: #260)

by Agnessa Babloyantz

This volume contains the proceedings of the workshop held in March 1990 at Austin, Texas on Self-Organization, Emerging Properties and Learning. The workshop was co-sponsored by NATO Scientific Affairs Division, Solvay Institutes of Physics and Chemistry, the University of Texas at Austin and IC2 Institute at Austin. It gathered representatives from a large spectrum of scientific endeavour. The subject matter of self-organization extends over several fields such as hydrodynamics, chemistry, biology, neural networks and social sciences. Several key concepts are common to all these different disciplines. In general the self-organization processes in these fields are described in the framework of the nonlinear dynamics, which also governs the mechanisms underlying the learning processes. Because of this common language, it is expected that any progress in one area could benefit other fields, thus a beneficial cross fertilization may result. In last two decades many workshops and conferences had been organized in various specific fields dealing with self-organization and emerging properties of systems. The aim of the workshop in Austin was to bring together researchers from seemingly unrelated areas and interested in self-organization, emerg{ng properties and learning capabilities of interconnected multi-unit systems. The hope was to initiate interesting exchange and lively discussions. The expectations of the organiziers are materialized in this unusual collection of papers, which brings together in a single volume representative research from many related fields. Thus this volume gives to the reader a wider perspective over the generality and ramifications of the key concepts of self­ organization.

Electronic Waste Recycling: Advances and Transformation into Functional Devices

by Roberto Baca-Arroyo

The consumption of technological products has increased in recent years owing to the modern industrial revolution, where people continue to acquire semiconductor device–based innovative hardware. However, this lifestyle may not be sustainable in the coming decades because it creates the global issue of electronic waste, caused by either mass-manufactured products or hardware that has worked in the past but is outdated now. This book presents accessible and organized literature on electronic waste recycling as an alternative route to engineering and realizing functional devices based on unusual material properties. It is a comprehensible study guide on the fundamentals of electronic waste usage and describes all aspects related to the state-of-the-art production and consumption cycles and the recycling of materials. The book explains the use of waste materials and the ways in which their unusual properties can be the basis of innovative devices for signal processing, sensing schemes, and reconfigurable operation.

Liapunov Functions and Stability in Control Theory (Communications and Control Engineering)

by Andrea Bacciotti Lionel Rosier

This book presents a modern and self-contained treatment of the Liapunov method for stability analysis, in the framework of mathematical nonlinear control theory. A Particular focus is on the problem of the existence of Liapunov functions (converse Liapunov theorems) and their regularity, whose interest is especially motivated by applications to automatic control. Many recent results in this area have been collected and presented in a systematic way. Some of them are given in extended, unified versions and with new, simpler proofs. In the 2nd edition of this successful book several new sections were added and old sections have been improved, e.g., about the Zubovs method, Liapunov functions for discontinuous systems and cascaded systems. Many new examples, explanations and figures were added making this book accessible and well readable for engineers as well as mathematicians.

Indistinguishable Classical Particles (Lecture Notes in Physics Monographs #44)

by Alexander Bach

Here, the concept of indistinguishability is defined for identical particles by the symmetry of the state, therefore applying to both the classical and the quantum framework. The author describes symmetric statistical operators and classifies these by means of extreme points. He derives de Finettis theorem for the description of infinitely extendible interchangeable random variables, and presents generalisations covering the Poisson limit and the central limit. Finally, a characterisation and interpretation of the integral representations of classical photon states in quantum optics are derived in abelian subalgebras, and unextendible indistinguishable particles are analysed in the context of non-classical photon states. Suitable for mathematical physicists and philosophers of science.

Messung von Ressourceneffizienz mit der ESSENZ-Methode: Integrierte Methode zur ganzheitlichen Bewertung

by Vanessa Bach Markus Berger Martin Henßler Martin Kirchner Stefan Leiser Lisa Mohr Elmar Rother Klaus Ruhland Laura Schneider Ladji Tikana Wolfgang Volkhausen Frank Walachowicz Matthias Finkbeiner

Eine belastbare Methode zu entwickeln, um den Ressourceneinsatz zu bewerten, ist das Ziel dieses Buches. Notwendig ist dies, da das starke Wirtschaftswachstum der letzten Jahrzehnte zu einer intensiven Beanspruchung natürlicher Ressourcen geführt hat. Mit ihrer steigenden Nutzung gehen auch zusätzliche Belastungen der Umwelt sowie Restriktionen der Verfügbarkeit von Ressourcen einher. Aus diesen Gründen ist ein effizienter Einsatz von Ressourcen als wichtiger Beitrag zu einer nachhaltigen Entwicklung erforderlich. Die ESSENZ-Methode (Integrierte Methode zur ganzheitlichen Berechnung/Messung von Ressourceneffizienz) wurde in einer Kooperation der Technischen Universität Berlin mit den Industriepartnern Daimler AG, Deutsches Kupferinstitut Berufsverband e. V., Evonik Industries AG, Siemens AG, ThyssenKrupp Steel Europe AG und Wissenschaftlicher Gerätebau Dr. Ing. Herbert Knauer GmbH entwickelt. Sie unterstützt die umfassende Messung und Bewertung von Ressourceneffizienz innerhalb der vier Dimensionen „Verfügbarkeit“, „Gesellschaftliche Akzeptanz“, „Umweltauswirkungen“ und „Nutzen“. Um diese vier Dimensionen wissenschaftlich abzubilden, werden 21 anwendbare Indikatoren entwickelt und vorgestellt. Die ESSENZ-Methode kann sowohl für die Analyse und Optimierung eines einzelnen Produktes als auch für den Vergleich mehrerer Produktalternativen verwendet werden. Ihre Anwendbarkeit ist für Metalle, und fossile Rohstoffe bereits erprobt.

Many-Electron Approaches in Physics, Chemistry and Mathematics: A Multidisciplinary View (Mathematical Physics Studies)

by Volker Bach Luigi Delle Site

This book provides a broad description of the development and (computational) application of many-electron approaches from a multidisciplinary perspective. In the context of studying many-electron systems Computer Science, Chemistry, Mathematics and Physics are all intimately interconnected. However, beyond a handful of communities working at the interface between these disciplines, there is still a marked separation of subjects. This book seeks to offer a common platform for possible exchanges between the various fields and to introduce the reader to perspectives for potential further developments across the disciplines. The rapid advances of modern technology will inevitably require substantial improvements in the approaches currently used, which will in turn make exchanges between disciplines indispensable. In essence this book is one of the very first attempts at an interdisciplinary approach to the many-electron problem.

Carbon Dioxide: Current Views and Developments in Energy/Climate Research 2nd Course of the International School of Climatology, Ettore Majorana Centre for Scientific Culture, Erice, Italy, July 16–26, 1982

by W. Bach A. J. Crane A. L. Berger A. Longhetto

The International School of Climatology of the "Ettore Majo­ rana Centre for Scientific Culture" at Erice was founded in 1979, with the aim of organising advanced courses and highly specialized seminars on current problems in the field of climatology. The first course, in March 1980, was devoted to climatic varia­ tions and variability, the understanding of which lies at the roots of modern climatological research. The publicity given to recent extremes of climate, which have had serious consequences for local populations, has led to an increased awareness of the practical importance of researching the causes and nature of climatic changes on all temporal and spatial scales. In recent decades it has become apparent that man himself is capable, mostly through industrial and agricultural activities, of causing climatic perturbations on both the local and global scales. Although these influences are as yet difficult to detect, it is clear that increasing release of C02 through the expanding use of fossil fuels for energy production is one activity that could lead to significant climatic change. Indeed, by this means, energy use has the potential of being the major influence on climate over the next century, so the choice of this aspect of climate-ener­ gy interactions as the topic of the Second Course of the Interna­ tional School of Climatology was an obvious one. It took place from 16 - 26 July, 1982.

The H Boson (Progress in Mathematical Physics #72)

by Costas Bachas Bertrand Duplantier Vincent Rivasseau

This volume provides a detailed description of the seminal theoretical construction in 1964, independently by Robert Brout and Francois Englert, and by Peter W. Higgs, of a mechanism for short-range fundamental interactions, now called the Brout-Englert-Higgs (BEH) mechanism. It accounts for the non-zero mass of elementary particles and predicts the existence of a new particle - an elementary massive scalar boson. In addition to this the book describes the experimental discovery of this fundamental missing element in the Standard Model of particle physics. The H Boson, also called the Higgs Boson, was produced and detected in the Large Hadron Collider (LHC) of CERN near Geneva by two large experimental collaborations, ATLAS and CMS, which announced its discovery on the 4th of July 2012.This new volume of the Poincaré Seminar Series, The H Boson, corresponds to the nineteenth seminar, held on November 29, 2014, at Institut Henri Poincaré in Paris.
