Abstract

In this paper, we investigate the influence of the Unruh effects on the coherence dynamics in an open quantum system which is subject to a nondissipative flip channel. We find that Unruh effect does not affect the known initial conditions which guarantee freezing of coherence, while it decreases the amount of preserved coherence.
