Effect of an external radiation field on the properties of the atoms and cavity field in the two-atom Tavis-Cummings model

We study the properties of atoms and cavity field in the two-atom Tavis--Cummings model where the two atoms interact with each other and are also driven by an external classical field. We consider the special case that the cavity is initially in a coherent state. The atomic inversion, the average photons number and the Mandel parameter in the driven Tavis--Cummings model are given and analysed numerically. We pay special attention to the dynamical behaviour of the atoms and the cavity field modified by the external field.
