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 l1-norm of coherence. This phenomenon is more evident for the uniform disorder distribution.

具有猝灭无序的Jaynes-Cummings模型中的量子相干动力学
我们将量子相干理论应用于三种类型的猝灭无序分布:均匀分布、高斯分布和柯西-洛伦兹分布的jayes - cummings模型。在一定条件下,我们观察到相干11范数的动力学有热阻尼行为。这种现象在均匀无序分布中更为明显。
