This book introduces readers to a variety of topics surrounding quantum field theory, notably its role in bound states, laser physics, and the gravitational coupling of Dirac particles. It discusses some rather sophisticated concepts based on detailed derivations which cannot be found elsewhere in the literature.
It is suitable for undergraduates, graduates, and researchers working on general relativity, relativistic atomic physics, quantum electrodynamics, as well as theoretical laser physics.

Readership: Undergraduates, graduates, and researchers working on general relativity, relativistic atomic physics, quantum electrodynamics, as well as theoretical laser physics.
Key Features:
- The book is an urgently needed modernization of the classic book of Bethe and Salpeter on One- and Two-Electron Atoms, which is hopelessly out of date by today's standards
- Also, the book introduces the reader to some rather sophisticated concepts from bound-state field theory, laser physics, and gravitational interactions, on the basis of detailed derivations which cannot be found elsewhere in the literature
- The book could be of interest to undergraduate students, graduates as well as established researchers
