标题： A new study of the Unruh effect

摘要： 我们在一个基于直接概率级计算的通用框架内重新审视了Unruh效应。 我们从惯性（闵可夫斯基）观察者和加速（里德纳）观察者的角度，重新推导了与质量标量场耦合的均匀加速Unruh-DeWitt单极探测器的跃迁率。 我们表明，在初始状态准备后经过有限时间的测量中，这两种观点给出相同的跃迁率。 我们确认，一个处于闵可夫斯基粒子热浴中的惯性探测器对加速探测器（其感知到的是里德纳粒子的热浴）的响应不同，除非在无质量场的情况下，所有时间都存在一致性。 最后，给出了新的跃迁率数值结果并进行了解释，突出了由于强制场最初处于闵可夫斯基真空态而引起的瞬态效应。 显示英文摘要

摘要： We revisit the Unruh effect within a general framework based on direct, probability-level calculations. We rederive the transition rate of a uniformly accelerating Unruh-DeWitt monopole detector coupled to a massive scalar field, from both the perspective of an inertial (Minkowski) observer and an accelerating (Rindler) observer. We show that, for a measurement at a finite time after the initial state is prepared, the two perspectives give the same transition rate. We confirm that an inertial detector in a thermal bath of Minkowski particles responds differently to the accelerated detector (which perceives a thermal bath of Rindler particles), except in the case of a massless field where there is agreement at all times. Finally, new numerical results for the transition rate are presented and explained, highlighting the transient effects caused by forcing the field to initially be in the Minkowski vacuum state.
