Entropy squeezing of a Jaynes–Cummings atom with the Glauber–Lachs state

Abstract

In this paper, we investigate the entropy squeezing of a two-level atom interacting with a quantum field prepared initially in the Glauber–Lachs state by using the Jaynes–Cummings model. We explore the effects of increasing the intensity of the thermal field over a fixed intensity of the coherent field on the entropy squeezing of the atom. We show that increasing the number of thermal photons in the coherent field has a destructive effect on the entropy squeezing of the atom.
