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.

Quantum entropy, is considered the main generalization of the Boltzmann classical entropy, proposed by von Neumann [1]
Our main interest is to investigate the evolution of the scaled atomic Wehrl entropy (AWE) of a single two-level atom and SU(1,1) quantum system in the presence of detuning parameter, which leads us to address the question: Can the AWE be used as a indicator of the entanglement and dynamical properties of the system in the presence of non-linear terms?
We have discussed the problem of the interaction between two-level atom and SU(1,1) quantum system
Summary
Quantum entropy, is considered the main generalization of the Boltzmann classical entropy, proposed by von Neumann [1]. Different entanglement measures and quantifiers for mixed and pure states have been proposed, such as the negativity and atomic Wehrl entropy. Atomic Wehrl entropy was used as an entanglement measure for a mixed state two-level system in the presence of intrinsic decoherence [24]. Our main interest is to investigate the evolution of the scaled atomic Wehrl entropy (AWE) of a single two-level atom and SU(1,1) quantum system in the presence of detuning parameter, which leads us to address the question: Can the AWE be used as a indicator of the entanglement and dynamical properties of the system in the presence of non-linear terms?.
