Cavity field spectra of the intensity-dependent two-mode Jaynes--Cummings model
The cavity field spectrum of a two-level atom interacting with two modes of the radiation field through intensity-dependent coupling in an ideal cavity is investigated. The results for the initial field in pure number states, coherent states, and squeezed vacuum states are calculated. The authors find that the frequency of one mode is tuned by the intensity of the other mode when the two modes are both in pure number states or coherent states. A complicated multipeak structure appears when both field modes are in a superposition of number states initially.
