Squeezing in nondegenerate two-photon processes in a cavity quantum electrodynamics of a three-level and a two-level Rydberg atom
N. Nayak · Physical Review A · 1993
The time evolution of squeezing in the two-photon interaction of a Rydberg atom with two nondegenerate modes of an ideal cavity is analyzed. The study compares the results from the two representations of the atom by a three-level system and an effective two-level system. We find the time evolution of the squeezing in the two systems to be different, including the regimes where the dynamics of the population are similar.
