摘要
In this work, we study the dynamics of quantum correlation for two uniformly accelerated atoms immersed in a bath of fluctuating massless scalar field with a perfectly reflecting plane boundary in the Minkowski vacuum. Firstly, the master equation that governs the system evolution is derived. Then we discuss the generation, revival and decay of quantum correlation for initial zero-correlation state and initial entangled state in various conditions and models. We contrast the behaviors of quantum correlation of accelerated atoms with that of static atoms in a thermal bath at the corresponding Unruh temperature and also make a comparison between behaviors of quantum correlation and entanglement behaviors. We find that behaviors of quantum correlation of uniformly accelerated atoms present some features distinct from that of static atoms immersed in a thermal bath, and behaviors of quantum correlation are more robust than that of entanglement.
