ABSTRACT:
In this paper, we study the dynamics of the atomic
inversion, scaled atomic Wehrl entropy and marginal atomic Wehrl density for a
single two-level atom interacting with SU(1,1) quantum system. We obtain the expectation values of the atomic variables using
specific initial conditions. We examine the effects of different parameters on
the scaled atomic Wehrl entropy and marginal atomic Wehrl density. We observe
an interesting monotonic relation between the different physical quantities for different values of the initial atomic position and
detuning parameter.
