Interaction of a twolevel atom with a quantized radiation field in the presence of a gravitational field
Abstract
The system of a twolevel atom interacting with a quantized radiation field in a gravitational field is studied by making use of a dynamical algebraic method. A full quantum treatment of the internal and external dynamics of the atom is given and an exact expression for the time evolution operator of the system is obtained. The influence of the gravitational field on the collapses and revivals of the atomic population, subPoissonian statistics, radiation force, atomic momentum diffusion, and squeezing of the radiation field is also investigated.
