**Book Description **Narosa Publishing House, 2011. Softcover. Book Condition: New. 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. Key Features ? Review Questions ? Problems with Solutions at the end of each chapter Table of Contents Preface / Introduction / The Dirac Equation and its Solutions / The Propagation Kernel and Feynman Diagrams / Quantum Electrodynamics / Radiative Corrections / Elements of Quantum Field Theory / The Scalar Fields / The Dirac Field / The Electromagnetic Field / Interaction between Fields / Recent Developments / Appendix A: List of Symbols and Notation / Appendix B: The Density of Final States / Bibliography / Subject Index. Printed Pages: 272. Bookseller Inventory # 68195
