Quantum Mechanics: An Introduction for Physicists

Book info: Quantum Mechanics: An Introduction for Physicists (Hardcover, 400 pages) – World Scientific Publishing Company, 2025. Language: English.

This book on Quantum Mechanics starts with the known field equation of Electrodynamics. Then comes the following steps: in the case of very weak fields the electromagnetic field equation becomes the quantum mechanical wave equation for single photons. This equation is generalized for massive particles (Klein–Gordon equation). The non-relativistic limit of this is the free Schrödinger equations. In this way the correspondence rules (leading from the Hamilton function to the Hamilton operator) are motivated.

On the whole, this book concentrates on applications, and on how things can be calculated . The formal structures are treated to the necessary extent.

The applications include all standard topics (including alpha-decay, the hydrogen atom including relativistic correction, angular moment coupling, the Stark effect) and proceed to many-body problems. This includes an introduction of the shell model of the atom and that of the atomic nucleus. Editorial Reviews About the Author Torsten Fliessbach is the Professor for Theoretical Physics, since 1979, at the University of Siegen, Germany. Born in Lauenburg (Pommern, Germany), he obtained his high school diploma (Abitur) at the Altes Realgymnasium in Munich, and his Diploma in Physics (1968) and PhD (1971) at the Technical University of Munich (TUM). He was awarded the scholarship of Studienstiftung des Deutschen Volkes (1966–1969) and, from 1971 to 1978, he worked as a research assistant at the Physics Department of TUM. From 1974 to 1975, Fliessbach was offered a research stint at the Lawrence Berkeley Laboratory (CA, USA) under the fellowship, Deutsche Forschungsgemeinschaft. In 1977, he was conferred Habilitation at TUM and, from 1978 to 1979, he was offered the Heisenberg fellowship. Prof. Fliessbach is especially known for authoring a series of textbooks in theoretical physics (first editions, in German), spanning the subjects on General Relativity, Mechanics, Electrodynamics, Quantum Mechanics and Statistical Physics.
