Atom - Photon Interactions: Basic Process and Appilcations

Atom-Photon Interactions: Basic Processes and Applications allows the reader to master various aspects of the physics of the interaction between light and matter. It is devoted to the study of the interactions between photons and atoms in atomic and molecular physics, quantum optics, and laser physics. The elementary processes in which photons are emitted, absorbed, scattered, or exchanged between atoms are treated in detail and described using diagrammatic representation. The book presents different theoretical approaches, including: \* Perturbative methods \* The resolvent method \* Use of the master equation \* The Langevin equation \* The optical Bloch equations \* The dressed-atom approach Each method is presented in a self-contained manner so that it may be studied independently. Many applications of these approaches to simple and important physical phenomena are given to illustrate the potential and limitations of each method.Content: Chapter 1 Transition Amplitudes in Electrodynamics (pages 5–66): Chapter 2 A Survey of Some Interaction Processes Between Photons and Atoms (pages 67–163): Chapter 3 Nonperturbative Calculation of Transition Amplitudes (pages 165–255): Chapter 4 Radiation Considered as a Reservoir: Master Equation for the Particles (pages 257–351): Chapter 5 Optical Bloch Equations (pages 353–405): Chapter 6 The Dressed Atom Approach (pages 407–514):

This analysis of the physical phenomena resulting from the interactions of atoms and photons discusses different theoretical approaches. Contributors discuss perturbative methods, resolvent methods, master equations, Langevin equations, optical Bloch equations and the dressed atom method. Allows the reader to master various aspects of the physics of the interaction between light and matter. This book focuses on the study of the interactions between photons and atoms in atomic and molecular physics, quantum optics, and laser physics. The idea of probability amplitude plays a central role in the quantum description of the time evolution of a physical process.
