Book Description
Superionic conductors are solids whose ionic conductivities approach, and in some cases exceed, those of molten salts and electrolyte solutions. This implies an un usual state of matter in which some atoms have nearly liquidlike mobility while others retain their regular crystalline arrangement. This liquid-solid duality has much appeal to condensed matter physicists, and the coincident development of powerful new methods for studying disordered solids and interest in superionic conductors for technical applications has resulted in a new surge of activity in this venerable field. It is the purpose of this book to summarize the current re search in the physics of superionic conduction. with special emphasis on those aspects which set these materials apart from other solids. The volume is aimed to wards the materials community and will, we expect, stimulate further research on these potentially useful substances. The usual characterization of the superionic phase lists high ionic conductivity; low activation energy; and the open structure of the crystal, with its interconne ted network of vacant sites available to one ionic species. To these, as we demon strate in this volume, should be added important dynami~ and collective effect~: the absence of well-defined optical lattice modes, the presence of a pervasive, low-energy excitation, an infrared peak in the frequency-dependent conductivity, unusual NMR prefactors, phase transitions, and a strong tendency for the mobile ion to be found between allowed sites.

Book Description
The following chapters present most of the lectures delivered at the NATO Advanced Studies Institute on "The Physics of Super ionic Conductors and Electrode Materials", held at Odense Univer sity's Mathematics Department between the 4th and 22nd of August, 1980. The aim of the organizing committee was to present in a rather detailed fashion the most recent advances in the computa tional mathematics and physics of condensed matter physics and to see how these advances could be applied to the study of ionically conducting solids. The first half of the meeting was mainly taken up with lectures. In the second week, working groups on the various aspects were set up, the students joining these groups being helped in the implementation of the lecture material. The leaders of these groups deserve special mention for the tremendous effort they put into this aspect of the meeting, particularly: Dr. Aneesur Rahman (Molecular Dynamics group) Dr. Fred Horne (Ion Transport group) Drs. Nick Quirke and David Adams (Monte Carlo methods) Dr. Heinz Schulz (Diffraction group) Dr. John Harding (Defect Calculations group) The Molecular Dynamics group achieved a certain amount of notoriety within the University by appearing to live in the terminal room.

Book Description
The book presents basic studies on ion transport properties of ionic conductive solid. It describes research on theory, modeling, simulation, crystalline structure, nuclear magnetic resonance, electric conduction, optical properties, and thermal measurement in this field. Superionic conductors are highly promising functional materials. As a stepping stone in the development of new superionic conductors that can be utilized as functinal materials efforts to reevaluate solid-interior diffusion and conduction phenomena of ions and molecules in a superionic conductor on the basis of basic physical properties, and to clarify mechanism governing these phenomena from a microscopic standpoint are important. How are diffusing ions associated with material structures within a superionic conductor? What types of interaction are diffusing ions undergoing with the host ions surrounding them? How important is the correlation among diffusing ions in their motion? The carefully presented detail of this book will be of value to research devoted to the understanding and control of functional materials such as superionic conductors.

Book Description
In 1966, E.H. Lieb and D.C. r1attis published a book on "Mathematical Physics in One Dimension" [Academic Press, New York and London] which is much more than just a collection of reprints and which in fact marked the beginnings of the rapidly growing interest in one-dimensional problems and materials in the 1970's. In their Foreword, Lieb and r~attis made the observation that " ... there now exists a vast literature on this subject, albeit one which is not indexed under the topic "one dimension" in standard indexing journals and which is therefore hard to research ... ". Today, the situation is even worse, and we hope that these Proceedings will be a valuable guide to some of the main current areas of one-dimensional physics. From a theoretical point of view, one-dimensional problems have always been very attractive. Many non-trivial models are soluble in one dimension, while they are only approximately understood in three dimensions. Therefore, the corresponding exact solutions serve as a useful test of approximate ma thematical methods, and certain features of the one-dimensional solution re main relevant in higher dimensions. On the other hand, many important phe nomena are strongly enhanced, and many concepts show up especially clearly in one-dimensional or quasi -one-dimensional systems. Among them are the ef fects of fluctuations, of randomness, and of nonlinearity; a number of in teresting consequences are specific to one dimension.

Book Description
The contribution of computer simulation studies to our understanding of proper ties of a wide range of condensed-matter systems is now well established. The Center for Simulational Physics has been hosting annual workshops with the in tent of bringing together some of the experienced practitioners in the field, as well as relative newcomers in the field, to provide a forum for the exchange of ideas and recent results. This year's workshop, the fourth in the series, was held at the University of Georgia, February 18-22, 1991. These proceedings are a record of the workshop and are published with the goal of timely dissemination of the papers to a wider audience. The proceedings are divided into three parts. The first part contains invited papers which deal with simulational studies of classical systems and includes an introduction to some new simulation techniques and special purpose comput ers as well. A separate section of the proceedings is devoted to invited papers on quantum systems including new results for strongly correlated electron and quantum spin models believed to be important for the description of high-T c superconductors. The contributed presentations comprise the final chapter.

Book Description
Starting from first principles, this book introduces the fundamental concepts and methods of dissipative quantum mechanics and explores related phenomena in condensed matter systems. Major experimental achievements in cooperation with theoretical advances have brightened the field and brought it to the attention of the general community in natural sciences. Nowadays, working knowledge of dissipative quantum mechanics is an essential tool for many physicists. This book -- originally published in 1990 and republished in 1999 and and 2008 as enlarged second and third editions -- delves significantly deeper than ever before into the fundamental concepts, methods and applications of quantum dissipative systems.This fourth edition provides a self-contained and updated account of the quantum mechanics of open systems and offers important new material including the most recent developments. The subject matter has been expanded by about fifteen percent. Many chapters have been completely rewritten to better cater to both the needs of newcomers to the field and the requests of the advanced readership. Two chapters have been added that account for recent progress in the field. This book should be accessible to all graduate students in physics. Researchers will find this a rich and stimulating source.

Book Description
Strongly Coupled Plasma Physics covers the proceedings of the 24th Yamada Conference on Strongly Coupled Plasma Physics, held from August 29 to September 2, 1989 at Hotel Mount Fuji near Lake Yamanaka on the outskirts of Tokyo. The book focuses on the reactions, technologies, interactions, and transformations of charged particles. The selection first offers information on phase transitions in dense astrophysical plasmas and plasma thermodynamics and the evolution of brown dwarfs and planets, as well as solidification of dense astrophysical plasmas, evolution of brown dwarfs, and structure of Jupiter. The text then examines the discovery of low mass objects in Taurus and topics in X-ray astronomy from observations with GINGA. The publication ponders on proton abundance in hot neutron star matter; thermonuclear reaction rates of dense carbon-oxygen mixtures in white dwarfs; and quantum simulation of superconductivity. The text also examines dynamic simulation of mixed quantum-classical systems and Monte-Carlo simulations for the surface properties of the strongly coupled one-component plasma. The selection is a dependable reference for readers interested in strongly coupled plasma physics.

Book Description
Charged particles in dense matter exhibit strong correlations due to the exchange and Coulomb interactions, and thus make a strongly coupled plasma. Examples in laboratory and astrophysical settings include solid and liquid metals, semiconductors, charged particles in lower dimensions such as those trapped in interfacial states of condensed matter or beams, dense multi-ionic systems such a superionic conductors and inertial-confinement-fusion plasmas . The aim of the conference was to elucidate the various physical processes involved in these dense materials. The subject areas covered include plasma physics, atomic and molecular physics, condensed matter physics and astrophysics.
