Quantum Physics

A modern two-volume set teaching students how to practically use quantum physics and theory. It focuses on problem solving, first presenting the fundamental knowledge, and then moving on to applications. Problems and solutions are integrated throughout the text. This two-volume set, naturally divided into two semester parts, contains a full modern graduate course in quantum physics. The idea is to teach graduate students how to practically use quantum theory by presenting the fundamental knowledge and gradually moving on to broad applications, including atomic, nuclear, relativistic and many-body physics, as well as subfields of current interest, such as quantum chaos and quantum entanglement. The author discusses topics that are not usually covered in standard textbooks and has written the book in such a way that every subject contains varying layers of difficulty, so that the instructor can decide where to stop. Problems and solutions are integrated throughout the text.
