Reduced quantum fluctuations and symmetry breaking in thermal Jaynes-Cummings model

We have examined the relationship between the field and atomic squeezing in the thermal Jaynes-Cummings model with an initially coherent atom. Also we have studied the influence of virtual-photon processes or thermal photons on the dynamical symmetry between the field and atomic squeezing shown in t...

More Information
Summary:We have examined the relationship between the field and atomic squeezing in the thermal Jaynes-Cummings model with an initially coherent atom. Also we have studied the influence of virtual-photon processes or thermal photons on the dynamical symmetry between the field and atomic squeezing shown in the absence of thermal photons.
