Analytical approach to the photon statistics in the thermal Jaynes-Cummings model with an initially unexcited atom
S. M. Chumakov, Marc von Kozierowski, J. J. Sánchez-Mondragón · Physical Review A · 1993
Simple analytical expressions for the time evolution of the mean photon number and its normally ordered variance for the case of an initially thermal cavity field coupled to an initially unexcited two-level atom are proposed. The possibility of appearance of sub-Poissonian field statistics is discussed.
