Dynamics of quantum coherence in the Jaynes–Cummings model with quenched disorder

Abstract

We have applied the quantum coherence theory to the Jaynes–Cummings model for three types of quenched disorder distribution: uniform, Gaussian, and Cauchy-Lorentz. Under certain conditions, we have observed a beat-damping behavior on the dynamics of the $l_1$-norm of coherence. This phenomenon is more evident for the uniform disorder distribution.
