Abstract
The acceleration-induced transparency (AIT) effect has been suggested recently to amplify the transition probability of the two-level detector 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 background field cannot be avoided completely in any experiments. Interestingly, we find that although the background thermal field generally degrades the entanglement between the detectors, the AIT effect can effectively protect it.
