For those who are interested in studying cavity QED, the book “Cavity Quantum Electrodynamics: The Strange Theory of Light in a Box” by Sergio M. Dutra gives an introduction to the quantum theory of light confined in a cavity. It starts with a field quantization of electromagnetic field, discusses its interaction with matter (i.e., Jaynes-Cummings model) and ends up with a discussion of the dissipation of the cavity mode.

I would recommend this to readers who has a basic knowledge of quantum optics.
