In this paper we study the entropy of a two-level atom driven by a detuned monochromatic laser field and damped by a squeezed vacuum. We obtain an exactly analytic solution of the model, by means of which we identify and numerically demonstrate the region of parameters where significantly large entanglement can be obtained. Also, the marginal distribution of the atomic Wehrl density is studied.

In a driven atom-cavity coupled system in which the two-level atom is driven by a classical field, the cavity mode which should be in a coherent state in the absence of its reservoir, can be squeezed by coupling to its reservoir. The squeezing effect is enhanced as the damping rate of the cavity is increased to some extent.
