By providing detailed explanations of challenging concepts for students and by offering professors an extensive list of subjects, the third edition of this best-selling quantum mechanics text follows the continuing evolution of physics in both esoteric and pragmatic directions. A new chapter, 15, develops the subject of relativistic waves, beginning with a review of basic relativistic concepts and continues with derivation of the Klein-Gordon equation. The chapter delves into the Dirac theory and the Dirac formulation of the four-dimensional spin operator, and concludes with a brief introduction to the covariant formulation of relativistic quantum mechanics. The revision also includes new descriptions and discussions of quantum-well configurations relevant to the quantum dot and the quantum wire and pertinent to semiconductor technology. Employing an assortment of symmetry principles, the transfer matrix method is developed and employed to regain the Kronig-Penny dispersion relation. The discussion of impurity semiconductors has been revised and is accompanied by a new subsection on the p-n junction. A new description of the Hartree-Fock model is included in the revision, which affords a method for obtaining approximate atomic wavefunctions and eigenenergies. This description complements the Thomas-Fermi model, which was new to the second edition. The third edition of Introductory Quantum Mechanics also includes a number of new intriguing problems many of which carry solutions, and a new, informative periodic chart appearing on the inside flap of the front cover. As with his previous editions, Liboff starts with a review of the most relevant elements of classical mechanics and proceeds through two parts that develop quantum theory. (view table of contents)

This updated and expanded edition offers a collective description of all aspects of kinetic theory Kinetic Theory: Classical, Quantum, and Relativistic Descriptions, Second Edition goes beyond the scope of other works in the field with a significantly broader array of applications. This superior reference addresses a wide range of disciplines, including aerospace, mechanical, and chemical engineering; solid state and laser physics; and controlled and astrophysical thermonuclear fusion. Topics covered include: * Entirely new material on kinetic properties of metals and amorphous media. * Exposition and analysis of the Liouville equation. * The Boltzmann equation, fluid dynamics, and irreversibility. * Kinetic equations with applications to plasmas, neutral fluids, and shock waves. * Elements of quantum kinetic theory and the many-body Green's function. * Relativistic kinetic theory--covariant Liouville equation * List of classical and quantum hierarchies of kinetic equations Support materials include problem sets at the end of each chapter, many of which provide self-contained descriptions of closely allied topics. Numerous appendices supply vector formulas and tensor notation, properties of special functions, physical constants, references, and a historical time chart. Kinetic Theory, Second Edition is an indispensable resource for physicists involved in plasma physics, condensed matter, and statistical mechanics; electrical engineers working with laser and solid state devices; and researchers in industry and academia. It is also an excellent text for graduate courses in these and other disciplines.
