This book provides material for courses in theoretical physics for undergraduate and graduate students specializing in condensed matter, including experimentalists who want a thorough theoretical background; the advanced part should be of interest to research workers too. A good first course in quantum mechanics is assumed. Here a variety of many-body phenomena in condensed matter are discussed, with special attention paid to the understanding of strong correlation effects. This requires a variety of theoretical tools (diagram expansions, groups, recursion methods and more). The text, which arose naturally from teaching, is eminently readable and the mathematical treatments are explained in enough detail to be followed easily. Proofs of all the relevant theorems are provided, but the main emphasis is always on the physical meaning or applicability of the results. Many examples are provided for illustration and also serve as worked problems.

This book is the first of a three-volume series written by the same author that aims to deliver a comprehensive and self-contained account of the vast field of solid-state physics. It goes far beyond most classic texts in the presentation of the properties of solids and experimentally observed phenomena, along with the basic concepts and theoretical methods used to understand them and the essential features of various experimental techniques. The first volume deals with the atomic and magnetic structure and the dynamics of solids, the second with those electric properties that can be understood in terms of the one-particle approximation, and the third with the effects due to interactions and correlations among electrons. This volume covers four major topics. After a brief history of solid-state physics, the introductory part presents the classification of condensed phases, describes the basic features of atoms as building blocks of solids, and analyzes how atoms bind together to form solids. The second part deals with structural aspects. The symmetries of crystalline solids and their consequences are covered in detail. Deviations from crystalline order either due to defects or in form of quasicrystalline or noncrystalline structures are also discussed. The third part is devoted to the theoretical description and experimental observation of lattice vibrations. Finally, magnetism due to localized magnetic moments is treated both phenomenologically and quantum mechanically. The text provides ample material for upper-level undergraduate and graduate courses. The book also serves as a valuable reference for researchers in the field of condensed matter physics.

This book provides an in-depth exposition of spin-stand microscopy of hard disk data which is a new technique recently developed and extensively tested by the authors of the book. Spin-stand microscopy is the first magnetic imaging technique where imaging is performed ex-situ on a rotating disk mounted on a spin-stand. This technique is one of the fastest scanning-based microscopy techniques. It is non-invasive and has nano-scale resolution. For these reasons, it provides unique capabilities for the visualization of magnetization patterns recorded on hard disks. This book is self-contained and it covers in sufficient details the basic facts of magnetic data storage technology, the principles and theory of spin-stand microscopy, its experimental implementations, as well as its applications in hard disk diagnostics, imaging of overwritten patterns, computer forensics of hard disk files, and data-dependent magnetic thermal relaxations of recorded magnetization patterns. This book will be a valuable reference for the magnetic data storage community, magnetic microscopy professionals as well as engineers and scientists involved in computer data forensics, commercial data recovery, and the design of archival data storage systems. Key features: - conceptual novelty of the technique and the demonstration of its wide scope of applications - detailed exposition of the principles of spin-stand magnetic microscopy - comprehensive discussions of novel image reconstruction techniques - demonstration of high resolution spin-stand images of hard disk data - presentation of sector-by-sector ex-situ forensics of hard disk files - extensive studies of data-dependent thermal relaxations of magnetization patterns recorded on hard disks Key features: - conceptual novelty of the technique and the demonstration of its wide scope of applications - detailed exposition of the principles of spin-stand magnetic microscopy - comprehensive discussions of novel image reconstruction techniques - demonstration of high resolution spin-stand images of hard disk data - presentation of sector-by-sector ex-situ forensics of hard disk files - extensive studies of data-dependent thermal relaxations of magnetization patterns recorded on hard disks.

The book is devoted to the consideration of the different processes taking place in thin films and at surfaces. Since the most important physico-chemical phenomena in such media are accompanied by the rearrangement of an intra- and intermolecular coordinates and consequently a surrounding molecular ensemble, the theory of radiationless multi-vibrational transitions is used for its description. The second part of the book considers the numerous surface phenomena. And in the third part is described the preparation methods and characteristics of different types of thin films. Both experimental and theoretical descriptions are represented. Media rearrangement coupled with the reagent transformation largely determines the absolute value and temperature dependence of the rate constants and other characteristics of the considered processes. These effects are described at the atomic or molecular level based on the multi-phonon theory, starting from the first pioneering studies through to contemporary studies. A number of questions are included at the end of many chapters to further reinforce the material presented. Unified approach to the description of numerous physico-chemical phenomena in different materials Based on the pioneering research work of the authors Explantion of a variety of experimental observations Material is presented at two levels of complexity for specialists and non-specialists Identifies existing and potential applications of the processes and phenomena Includes questions at the end of some chapters to further reinforce the material discussed.
