Effect of detuning on deep squeezing of coherent light in the Jaynes-Cummings model
Chang-qi Cao, Ding Xiao-hong · Physical Review A · 1992
The effect of detuning on squeezing of coherent light is studied in the Jaynes-Cummings model and in the large-N (mean photon number) limit. Analytical formulas for quadrature variances are obtained both in the one-photon and two-photon transition cases. In the former case, small detuning only has a small (unfavorable) effect on squeezing. In the latter case, however, the effect of detuning is significant. No squeezing will occur at resonance, and by the presence of detuning, there will be a series of minima appearing in the suppressed quadrature variance during time evolution as happens in the one-photon transition case, with the limit of this series tending to zero. The explicit expressions for the kth minima are also given for fairly large k.
