摘要/Abstract

摘要： 研究了盎鲁效应对非马尔科夫环境下2个独立狄拉克粒子量子纠缠的影响，结果表明只在某些特定情况下发生纠缠突然死亡和复活。当探测器处在非惯性系,盎鲁效应会对纠缠的复活现象产生很大影响。探测器处在非惯性系中的加速度不大于一个“临界点”,纠缠死亡和复活仍会出现,而当加速度大于这个“临界点”，纠缠死亡和复活现象不再发生。对此提出了一个合理的解释：盎鲁效应将会影响非马尔科夫环境的记忆效应，也会影响此时环境中量子纠缠的出现及其增长率。

Abstract: Influence of Unruh effect on quantum entanglement of two Dirac particles in non-Markovian environment is investigated. Results show that the sudden death and revival of entanglement occurs only in some special cases. When the detector is in noninertial frame, Unruh effect will has a great influence on the entanglement revival phenomenon. When the acceleration of detector in noninertial system is not more than a “critical point”, the sudden death and revival of entanglement will still occur, while it will not occur when the acceleration is greater than the “critical point”. A reasonable explanation is proposed that Unruh effect will affect the memory effect of non-Markovian environment, and the appearance of quantum entanglement and its growth rate in the environment.

Key words: quantum entanglement; non-Markovian environment; Unruh effect; noninertial frame; memory effect
