论文摘要
我们量化了两个加速检测器之间的量子相关性，该检测器耦合到腔体中的标量场。已经意识到，加速的检测器将体验到一个热浴，这被称为“未造成效应”。我们检查了有关温度或加速度的量子相关性的相似性和差异。随着检测器的加速度（分别温度）的增加，纠缠在某些瞬间下降至零，但是可以扩增相互信息（分别不和）。随着加速度的增加，但在相反的方向上，量子相关性衰减。重要的是，我们还揭示了在某些非平衡场景中可能出现较大的量子相关性，在某些非平衡场景中，加速度差或耦合差异显着。
We quantify the quantum correlations between two accelerated detectors coupled to a scalar field in a cavity. It has been realized that an accelerated detector will experience a thermal bath, which is termed the Unruh effect. We examine the similarities and differences for quantum correlations regarding either temperature or acceleration. As the accelerations (resp. temperatures) of the detectors increase, the entanglement decreases to zero at some instant but the mutual information (resp. discord) can be amplified. As the accelerations increase but are in opposite directions, the quantum correlations decay. Importantly, we also reveal that larger quantum correlations can appear in certain nonequilibrium scenarios in which either the acceleration difference or the coupling difference becomes significant.
