| Abstract: | An alternative approach to the Jaynes-Cummings model (JCM) with dissipation at a finite environmental temperature is presented in terms of a new master equation under Born-Markovian approximation. An analytic solution of the dissipation JCM is obtained. A variety ofphysical quantities of interest are calculated analytically. Dynamical properties of the atom and the field are investigated in some detail. It is shown that both cavity damping and environmental temperature strongly affect nonclassical effects in JCM, such as collapse and revivals of the atomic inversion, oscillations of the photon-number distribution, quadrature squeezing of the field and sub-Poissonian photon statistics. |
