Angular Momentum Techniques in Quantum Mechanics (Fundamental Theories of Physics)

A course in angular momentum techniques is essential for quantitative study of problems in atomic physics, molecular physics, nuclear physics and solid state physics. This book has grown out of such a course given to the students of the M. Sc. and M. Phil. degree courses at the University of Madras. An elementary knowledge of quantum mechanics is an essential pre-requisite to undertake this course but no knowledge of group theory is assumed on the part of the readers. Although the subject matter has group-theoretic origin, special efforts have been made to avoid the gro- theoretical language but place emphasis on the algebraic formalism dev- oped by Racah (1942a, 1942b, 1943, 1951). How far I am successful in this project is left to the discerning reader to judge. After the publication of the two classic books, one by Rose and the other by Edmonds on this subject in the year 1957, the application of angular momentum techniques to solve physical problems has become so common that it is found desirable to organize a separate course on this subject to the students of physics. It is to cater to the needs of such students and research workers that this book is written. A large number of questions and problems given at the end of each chapter will enable the reader to have a clearer understanding of the subject.

Quantum Mechanics describes the phenomena that matter and light exhibit on an atomic scale and so the study of atomic physics, nuclear physics and solid state physics are impossible without a clear understanding of the basic concepts and formalism of Quantum Mechanics. Since Physics deals essentially with numbers – the measurement of physical quantities and the calculations of these quantities on the basis of a theoretical framework – adequate attention has been paid to computation and numerical exercises. This book aims to promote a comprehensive understanding of the subject with illustrative examples.

The appendices F, G and H are the elaboration of the mathematical tools - Dirac delta function, angular momentum in spherical coordinates and orthogonal curvilinear coordinates - that are used in the text. The appendix I on symmetry principles and conservation laws is an important and vital part of physics since almost all laws of nature originate from symmetries.

RELATIVISTIC QUANTUM MECHANICS AND QUANTUM FIELD THEORY deals with the single particle relativistic wave equations and the elements of quantum field theory. The Klein-Gordon equation is discussed briefly and elaborately the Dirac equation, its free particle solutions and Feynman s positron theory with a view to emphasize how the intuitive approach of Feynman has enormously simplified the calculations in Quantum Electrodynamics the interaction of radiation with matter by the introduction of Feynman diagrams. It is shown that Feynman s approach is equivalent to the other more general approach of quantum field theory and the equivalence of the two approaches has been demonstrated through the S-matrix formalism which leads to the Feynman diagrams by the application of Wick s theorem. How the quantum field theory is stretched beyond quantum electrodynamics to include electro weak interactions and strong interactions and how it leads to the formulation of the standard model of elementary particles are briefly discussed.
