Abstract
The acceleration-induced transparency (AIT) effect has been suggested recently to amply the transition probability of the two-level detctor and offers a potential avenue for the experimental detection of the Unruh effect. In this paper, we explore the influence of the AIT effect on quantum entanglement between two detectors accelerated in a thermal field background, since the thermal backgound field cannot be avoided completely in any experiments. Interestingly, we find that although the backgound thermal field generally degrade the entanglement between the detectors, the AIT effect can effectively protect it.
