Contribution

It introduces a deformed cavity model with an external microwave field and analyzes nonclassical properties, extending the standard Jaynes-Cummings framework.

Findings

Nonclassical properties are significantly affected by the coupling constant.

Kerr medium and intensity-dependent coupling influence quantum entanglement.

Field squeezing varies with system parameters and external influences.

Abstract

In this article, we explore the interaction between a V-type atom inside a single mode deformed cavity field in the presence of an external microwave field. The Hamiltonian describing the system is derived from the standard Jaynes-Cummings model by deforming the field operators based on the Kerr-induced interaction. The total and reduced density matrices are obtained and the temporal evolution of nonclassical properties such as the Mandel Q parameter, quantum entanglement, and the position-momentum uncertainty relation (squeezing) of the field are examined. The impacts of coupling constant, generalized Kerr medium, and the intensity-dependent coupling function on the nonclassical indicators are thoroughly analyzed.
