## Light: Waves, photons, atoms, Volume 1Starting from a rather elementary level, this volume includes a self-contained, concise introduction into the quantum theory of matter and develops in detail the quantum theory of light. It presents the approaches needed to cope with the various interaction processes between light and matter and illustrates them by various examples. Recent developments such as the dynamic Stark effect and quantum beats are also covered. |
