论文摘要
我们通过考虑以任意但独立且恒定的速度移动的一对iNRUH-DEWITT检测器来研究相对运动对纠缠收获的影响,均与真空标量场线性相互作用。在弱耦合近似中工作,我们发现消极率是检测器相对速度的(非元素)功能,及其能量差距和最小的分离。我们发现参数区域随着速度的最大速度增加,然后减小,然后在某些过高的速度下达到零。在任何给定的相对速度下,收获的纠缠与检测器能量隙(以足够高的值)和两个检测器最接近接近的距离成反比。
We investigate the effects of relative motion on entanglement harvesting by considering a pair of Unruh-Dewitt detectors moving at arbitrary, but independent and constant velocities, both linearly interacting with the vacuum scalar field. Working within the weak coupling approximation, we find that the Negativity is a (non-elementary) function of the relative velocity of the detectors, as well as their energy gaps and minimal separation. We find parameter regions where Negativity increases with velocity up to a maximum and then decreases, reaching zero at some sublight velocity. At any given relative velocity, the harvested entanglement is inversely correlated with the detector energy gap (at sufficiently high values) and the distance of closest approach of two detectors.
