This comprehensive primer by a Nobel Physicist covers the electronic spectra of metals, electrical and thermal conductivities, galvanomagnetic and thermoelectrical phenomena, the behavior of metals in high-frequency fields, sound absorption, and Fermi-liquid phenomena. Addressing in detail all aspects of the energy spectra of electrons in metals and the theory of superconductivity, it continues to be a valuable resource for the field almost thirty years after its initial publication. Targeted at undergraduate students majoring in physics as well as graduate and postgraduate students, research workers, and teachers, this is an essential reference on the topic of electromagnetism and superconductivity in metals. No special knowledge of metals beyond a course in general physics is needed, although the author does presume a knowledge of quantum mechanics and quantum statistics.

In this Ph. D. Thesis we concentrate on the study of the extension of the AdS/CFT correspondence to theories with less supersymmetry. In particular, we search for the possibility of adding supersymmetric D-branes in type IIB supergravity solutions which are dual to N=1 supersymmetric gauge theories in four dimensions. In the probe approximation we perform a systematic analysis of the possible supersymmetric D-brane configurations in backgrounds dual to N=1 superconformal field theories, firstly in the AdS_5xY^{p,q} solutions and then in their generalisation to the AdS_5xL^{a,b,c} backgrounds. Some checks of the correspondence between D-brane configurations and chiral operators of the dual gauge theory are performed. We also analyse the possible supersymmetric D5-brane configurations dual to defects (of codimension one and two) in N=1 SYM theory in the framework of the Maldacena-Nunez solution. Beyond the probe approximation, we develop techniques in order to take into account the backreaction undergone by the type IIB supergravity solutions (dual to N=1 superconformal field theories and their extensions to cascading theories) due to the addition of a number of flavour branes of the same order as the number of colour branes which generate the unflavour background. The dual interpretation of those flavour branes is given in terms of dynamical fields transforming in the fundamental representation of the gauge group. Several gauge theories features are matched, like beta functions, anomalies and the duality cascade which describes the RG flow of the cascading field theories.

Introducing the subject of superfluid helium three and polarized liquid helium three, this book is devoted to modern problems in many body physics specific to the quantum fluid helium three. Relationships between properties of helium three and topics in other fields are established including superconductivity, non-linear dynamics, acoustics, and magnetically polarized quantum systems. Among the chapters in this collection one finds valuable reference material and original research not published elsewhere. Advanced research topics are presented in a pedagogical manner, in considerable depth, and with appropriate introductory material sufficiently general to be suitable to the non-specialist.

New models for dislocation structure and motion are presented for nanocrystals, nucleation at grain boundaries, shocked crystals, interphase interfaces, quasicrystals, complex structures with non-planar dislocation cores, and colloidal crystals. A review of experimentally established main features of the magnetoplastic effect with their physical interpretation explains many diverse results of this type. The model has many potential applications for forming processes influenced by magnetic fields. • Dislocation model for the magnetoplastic effect • New mechanism for dislocation nucleation and motion in nanocrystals • New models for the dislocation structure of interfaces between crystals with differing crystallographic structure • A unified view of dislocations in quasicrystals, with a new model for dislocation motion • A general model of dislocation behavior in crystals with non-planar dislocation cores • Dislocation properties at high velocities • Dislocations in colloidal crystals

``Semimetals'' presents, for the first time in the literature, a consistent and unifying treatment of semimetals (As, Bi, Sb, Bi-Sb alloys, graphite and its compounds). It describes their structural features and their electric, magnetic, galvanomagnetic, thermoelectric, optical, magneto-optical, acoustic, thermal, and mechanical properties on the basis of modern concepts of the electron and phonon energy spectra. The book discusses in detail the character of the changes in the energy spectrum and properties of semimetals due to temperature variations, application of a magnetic field, pressure, anisotropic strain, doping by donor, acceptor and neutral impurities, which indicate how the above properties may be altered and how materials with preassigned parameters can be produced. Furthermore, it discusses specific phenomena associated with low dimensionality and the very low carrier density, such as quantum oscillations and magnetoplasma behaviour.

Many notions and results presented in the previous editions of this volume have since become quite popular in applications, and many of them have been “rediscovered” in applied papers. In the present 3rd edition small changes were made to the chapters in which long-time behavior of the perturbed system is determined by large deviations. Most of these changes concern terminology. In particular, it is explained that the notion of sub-limiting distribution for a given initial point and a time scale is identical to the idea of metastability, that the stochastic resonance is a manifestation of metastability, and that the theory of this effect is a part of the large deviation theory. The reader will also find new comments on the notion of quasi-potential that the authors introduced more than forty years ago, and new references to recent papers in which the proofs of some conjectures included in previous editions have been obtained. Apart from the above mentioned changes the main innovations in the 3rd edition concern the averaging principle. A new Section on deterministic perturbations of one-degree-of-freedom systems was added in Chapter 8. It is shown there that pure deterministic perturbations of an oscillator may lead to a stochastic, in a certain sense, long-time behavior of the system, if the corresponding Hamiltonian has saddle points. The usefulness of a joint consideration of classical theory of deterministic perturbations together with stochastic perturbations is illustrated in this section. Also a new Chapter 9 has been inserted in which deterministic and stochastic perturbations of systems with many degrees of freedom are considered. Because of the resonances, stochastic regularization in this case is even more important.

This book is devoted to the mathematical studies of stochastic systems with quasi-stationary phenomena which have applications to population dynamics or epidemic models. In addition to its use for the research and reference purposes, the book can also be used in special courses on the subject and as a complementary reading in general courses on stochastic processes. In this respect, it may be useful for specialists as well as doctoral and advanced undergraduate students.
