Photon Statistics in Thermal Multiphoton Jaynes-Cummings Models with an Initially Excited Atom
Marc von Kozierowski, S. M. Chumakov, J. J. Sánchez-Mondragón · Journal of Modern Optics · 1993
Analytical expressions for the time evolution of the mean photon number and normally ordered photon number variance for the case of an initially thermal cavity field coupled to an initially excited two-level atom with m-photon transitions are proposed. The emergence of sub-Poissonian field statistics is discussed.
