TL;DR: In this article, the exact expressions for the atom-field probability amplitudes in the rotating-wave approximation are presented, and exact solutions are employed in the study of the quantum collapse and revivals of the atomic coherence.
Abstract: Interactions of two two-level atoms with a single-mode quantized radiation field are studied, and exact expressions for the atom-field probability amplitudes in the rotating-wave approximation are presented. These solutions are employed in the study of the quantum collapse and revivals of the atomic coherence.

TL;DR: Theoretically, it is shown that the appearance of a spectrum, as opposed to a single Rabi resonance, is due to the fact that the phase of the field changes discretely by ..pi.. radians, rather than sinusoidally.
Abstract: By use of a double-resonance technique, a spectrum of Rabi resonances has been observed. These resonances are enhancements in the dynamic response of a quantum system's population to rapid changes in the phase of a perturbing electromagnetic field. Theoretically, it is shown that the appearance of a spectrum, as opposed to a single Rabi resonance, is due to the fact that the phase of the field changes discretely by ..pi.. radians, rather than sinusoidally. In the presence of ..pi..-radian phase changes, the quantum system's dynamic response is found to be similar to a damped harmonic oscillator driven by a deltafunction force term. In this harmonic-oscillator approximation the Rabi-resonance spectrum arises naturally, resulting from a resonant enhancement of the atomic coherence.
