Macroscopic Quantum Electrodynamics

Abstract

The theory of macroscopic quantum electrodynamics is developed which forms the basis for the analysis of dispersion forces presented in this book. Basic concepts of classical electrodynamics and quantum electrodynamics in free space are recalled. Using these as a guiding principle, we then construct a consistent theory of the quantised electromagnetic field in the presence of magnetoelectric media based on the classical Green’s tensor for the electromagnetic field. Atom–field interactions are implemented via the minimal and multipolar coupling schemes.
