Solid State Physics : Principles and Modern Applications Part I Crystal Structures Lattice Vibrations Free Electron Theory of Metals Elements of Band Theory Use of Elementary Group Theory in Calculating Band Structure More Band Theory and the Semi classical Approximation Semiconductors Dielectric Properties of Solids Magnetism in Solids Part II Magnetic Ordering and Spin Waves Many Body Interactions: Introduction Many Body Interactions: Green’s Function Method Semi classical Theory of Electrons Electrodynamics of Metals Superconductivity The Fractional Quantum Hall Effect: The Paradigm for Strongly Interacting Systems Correlation Diagrams: An Intuitive Approach to Interactions in Quantum Hall Systems. This book provides the basis for a two semester graduate course on solid state physics. The first half presents all the knowledge necessary for a one semester survey of solid state physics but in greater depth than most introductory solid state physics courses. The second half includes most of the important research over the past half century covering both the fundamental principles and most recent advances. This new edition includes the latest developments in the treatment of strongly interacting two dimensional electrons and discusses the generalization from small to larger systems. The book provides explanations in a class tested tutorial style and each chapter includes problems reviewing key concepts and calculations. The updated exercises and solutions enable students to become familiar with contemporary research activities such as the electronic properties of massless fermions in graphene and topological insulators.
