Quantum Discord and Entanglement for Two Atoms in a Kerr Medium and Stark Shift
M. Youssef
Abstract:. This study analyzes the effect of the Kerr medium and Stark shift on the entanglement between two two-level atoms and a single-mode cavity in a quantum model. The findings demonstrate that the entanglement between the atoms varies periodically over time, with the periods affected by the Kerr medium and Stark shift. The Kerr medium and Stark shift hinder atom disentanglement, resulting in a prolonged stationary entangled state. The Stark shift can also enhance atom-atom entanglement for partially entangled st… Show more
