Rh. Xie et Go. Xu, REDUCED QUANTUM FLUCTUATIONS AND SYMMETRY-BREAKING IN THERMAL JAYNES-CUMMINGS MODEL, Optics communications, 128(1-3), 1996, pp. 48-54
We have examined the relationship between the field and atomic squeezi
ng in the thermal Jaynes-Cummings mode!with an initially coherent atom
, Also we have studied the influence of virtual-photon processes or th
ermal photons on the dynamical symmetry between the, field and atomic
squeezing shown in the absence of thermal photons.
