| dc.description | Quantum electrodynamics (QED) has been considered as crucial area of study in quantum optics, due to the inherently interesting and far-reaching implications resulting from the exploration of the fundamental characteristics of light-matter interaction1 . In a cavity QED, the typical representation is that an atom interacts with a single near-resonant quantized mode of the electromagnetic feld. Terefore, the model describes coupling between a two-level particle and a harmonic oscillator. Te study of the interaction is analytically obtained by the solvable Jaynes-Cummings model (JCM)2, | |
| dc.description.abstract | Quantum entanglement and atomic coherence are examined for a system consisting of a four-level atom (FLA) interacted with a nonlinear quantum field. We assume that the FLA-field coupling, Kerr medium and quantified field are all f -deformed with full nonlinear formalism. We consider N-configuration and cascade (C)-configuration of the FLA. We explore the impact of field deformation and Kerr medium on the dynamics of the quantumness measures when the quantized field is initially prepared in a deformed coherent state without and with Kerr medium effect. Moreover, we examine the statistical properties of the radiation field using the second order correlation function. The results indicate how the considered quantumness measures in the FLA–field system can be manipulated and controlled through the parameters of the quantum model.
