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。当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。
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 occur only in some special cases. When the detector is in noninertial frame, Unruh effect 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 still occur, while they don't occur when the acceleration is greater than the critical point. A reasonable explanation is proposed that Unruh effect affects the memory effect of non-Markovian environment, the appearance of quantum entanglement and its growth rate in the environment.
