Advanced Quantum Mechanics covers topics such as many-body systems, relativistic wave equations, and relativistic quantum fields. The rigorous presentation that the author already demonstrated in Quantum Mechanics I is supplemented by the inclusion of all intermediate steps, numerous application examples, and exercises. The book lays a foundation for further study in solid-state, nuclear, and particle physics. The 5th edition has been carefully revised, expanded, and standardized in its graphical representation.
