利用两个惯性Unruh-DeWitt探测器研究了（1 + 1）维时空中存在运动Dirichlet边界条件（即镜像时空）的无质量标量场真空中的纠缠提取现象。我们考虑了这些加速镜的各种非平凡轨迹，并发现(1)类似于最近在黑洞中看到的纠缠抑制现象，以及(2)在某些体制中与轨迹无关的纠缠增强。我们证明了探测器与场的线性耦合和导数耦合的定性结果是相同的。ar X iv:1 81 0。[au:] [au:] [au:] [au：
We study the phenomenon of entanglement extraction from the vacuum of a massless scalar field in (1 + 1) dimensional spacetime in presence of a moving Dirichlet boundary condition, i.e. mirror spacetime, using two inertial Unruh-DeWitt detectors. We consider a variety of non-trivial trajectories for these accelerating mirrors and find (1) an entanglement inhibition phenomenon similar to that recently seen for black holes, as well as (2) trajectory-independent entanglement enhancement in some regimes. We show that the qualitative result obtained is the same for both linear and derivative couplings of the detector with the field. ar X iv :1 81 0. 07 35 9v 3 [ qu an tph ] 1 0 Ju l 2 01 9
