An Introduction to Advanced Quantum Physics

An Introduction to Advanced Quantum Physics presents important concepts from classical mechanics, electricity and magnetism, statistical physics, and quantum physics brought together to discuss the interaction of radiation and matter, selection rules, symmetries and conservation laws, scattering, relativistic quantum mechanics, apparent paradoxes, elementary quantum field theory, electromagnetic and weak interactions, and much more.This book consists of two parts:Part 1 comprises the material suitable for a second course in quantum physics and covers:backup out PBE_20210409_180616.xml PKN_20210409_180616.xml PVA_20210409_180616.xml work Electromagnetic Radiation and Matterbackup out PBE_20210409_180616.xml PKN_20210409_180616.xml PVA_20210409_180616.xml work Scatteringbackup out PBE_20210409_180616.xml PKN_20210409_180616.xml PVA_20210409_180616.xml work Symmetries and Conservation Lawsbackup out PBE_20210409_180616.xml PKN_20210409_180616.xml PVA_20210409_180616.xml work Relativistic Quantum Physicsbackup out PBE_20210409_180616.xml PKN_20210409_180616.xml PVA_20210409_180616.xml work Special TopicsPart 2 presents elementary quantum field theory and discusses:backup out PBE_20210409_180616.xml PKN_20210409_180616.xml PVA_20210409_180616.xml work Second Quantization of Spin 1/2 and Spin 1 Fieldsbackup out PBE_20210409_180616.xml PKN_20210409_180616.xml PVA_20210409_180616.xml work Covariant Perturbation Theory and Applicationsbackup out PBE_20210409_180616.xml PKN_20210409_180616.xml PVA_20210409_180616.xml work Quantum ElectrodynamicsEach chapter concludes with problems to challenge the students' understanding of the material.This text is intended for graduate and ambitious undergraduate students in physics, material sciences, and related disciplines.

This book is intended for undergraduates who take a third and fourth quarter of quantum physics, and thus limits itself to those topics that are absolutely necessary for understanding elementary particle physics and condensed matter. The book consists of two parts: the first part presents radiation theory, scattering, symmetries, relativistic quantum physics, and special topics; the second part presents second quantization, covariant perturbation theory, and simple applications to the weak interaction and quantum electrodynamics.
