标题： Influence of field mass and acceleration on entanglement generation

摘要： 我们探讨了在大质量标量场中进行匀加速和圆周运动的两个探测器的纠缠动力学，同时研究了反Unruh效应对纠缠获取的影响。 与传统的弱反Unruh效应的理解相反，即纠缠通常会增加，我们观察到探测器之间的最大纠缠并不严格依赖于探测器加速度。 特别是在低加速度情况下，纠缠最大值的波动与探测器跃迁率的波动表现出强烈的相关性。我们还发现，探测器的最大纠缠随着场质量的减小而增加。 新颖的是，我们的研究结果表明，在(3+1)维大质量标量场中不存在强反Unruh效应。 相反，由加速度引起的热效应导致探测器纠缠最大值下降。 显示英文摘要

摘要： We explore the entanglement dynamics of two detectors undergoing uniform acceleration and circular motion within a massive scalar field, while also investigating the influence of the anti-Unruh effect on entanglement harvesting. Contrary to the conventional understanding of the weak anti-Unruh effect, where entanglement typically increases, we observe that the maximum entanglement between detectors does not exhibit a strict monotonic dependence on detector acceleration. Particularly at low accelerations, fluctuations in the entanglement maxima show a strong correlation with fluctuations in detector transition rates.We also find that the maximum entanglement of detectors tends to increase with smaller field mass. Novelly, our findings indicate the absence of a strong anti-Unruh effect in (3+1)-dimensional massive scalar fields. Instead, thermal effects arising from acceleration contribute to a decrease in the detector entanglement maximum.
