Abstract

We discuss the time evolution of the atomic inversion of a system of N two-level atoms interacting with a single quantized field mode in a high-Q cavity. We present both the operator solution and analytical expressions for the corresponding revivals, and extend the well-known picture of the single-atom (JCM). The operator solution is perturbative based on the approximate dynamic symmetry of this model¹; the analytical revival method was introduced recently.²
