Описание: "We can only hope that more such striking expositions will be written." -- Bulletin of the American Mathematical Society
This is a systematic, covariant treatment of the classical theories of particle motion, fields, and the interaction of fields and particles. Particular attention is given to the interaction of charged particles with the electromagnetic field. The treatment throughout the book is relativistic; the author attempts, as much as possible, a coordinate free (or covariant) form of the equations both for particles and the fields. The book opens with an extensive discussion of space-time, Lorentz transformations, Lorentz-group and tensor and spinor fields. This material is essential to the understanding of many branches of theoretical physics, in particular relativistic quantum theory. Chapter II describes various relativistic forms of the fundamental problem of dynamics: describing the trajectories of particles for given external forces. The general dynamical principles to obtain the field equations and the important problems of the conservation laws are discussed in Chapter III.The second part of the book (Chapters IV-VI) is devoted to a lucid treatment of the interactions of fields and particles. Chapter IV deals with equations of motion and their solutions (the so-called Cauchy problem), focusing on the solution of field equations with Green's functions using Dirac formalism. The problem of feedback between particles and fields (radiation and radiation reaction) is taken up in Chapter V, as are questions concerning the limitations of classical field theories and classical dynamics. Dr. Barut concludes the book with an excellent exposition of the purely mechanical approach to the problem of the interactions of charged particles -- the so-called action-at-a-distance formulation of electrodynamics. Problems, alternate proofs, and additional topics are included at the end of each chapter, where a useful bibliography is also provided. A general bibliography appears at the end of the book.

Описание:

This systematic introduction to quantum electrodynamics focuses on the interaction of radiation with outer electrons and nuclei of atoms and molecules, answering the long-standing need of chemists and physicists for a comprehensive text on this highly specialized subject.
Geared toward postgraduate students in the chemical sciences who require an understanding of quantum electrodynamics as applied to the interpretation of optical experiments on atoms and molecules, the text offers a detailed explanation of the quantum theory of electromagnetic radiation and its interaction with matter. It features formal derivations of the quantized field matrix elements for an amazing number of laser-molecule interaction effects: one- and two-photon absorption and emission; Rayleigh and Raman scattering; dispersion forces in a radiation field; radiation-induced chiral discrimination; both linear and nonlinear optical processes such as Coherent Anti-Stokes Raman Scattering (CARS) and laser-induced optical rotation; self-energy; and the Lamb shift.
Virtually a one-volume encyclopedia, this self-contained book starts with first principles, making it useful both for students and experts in the field. Molecular physicists, quantum chemists, chemical physicists, and theoretical chemists will find essential calculation techniques explained with the greatest clarity.
