Two-level system interacting with a finite-bandwidth thermal cavity mode
J. I. Cirac, Helmut Ritsch, P. Zoller · Physical Review A · 1991
The interaction of a two-level system with a single quantized mode of the radiation field of finite bandwidth in a thermal state and coupled to background vacuum modes is considered theoretically. A hierarchy of equations for atom-field moments is derived and solved in terms of continued fractions. The population inversion, the spectrum of resonance fluorescence, and the photon statistics of the cavity mode are calculated.
