论文摘要
从量子意义上讲，真空不是一个空的空隙，而是充满虚拟粒子（字段）。它可能具有远程特性，被改变，甚至发生相变。建议通过在大空间体积上分配物质来探测量子真空的远距离性能。在这里，我们研究了一个最简单的例子，即，两个均匀加速的unruh-dewitt探测器，它们在空间上分离，并检查由检测器之间的耦合和波动磁场之间的耦合引起的探测器间相互作用能量，以查看与远距离更改的较长范围的跨度通过相应的彼此相关的相关性。 Our results show that when the inter-detector separation is much larger than the thermal wavelength of the Unruh thermal bath, the inter-detector interaction displays a completely new behavior, which, as compared with that of the inertial detectors, is surprisingly exclusively acceleration-dependent, signaling a new phase of the vacuum in which its imprint as seen by two inertial observers seems to be completely wiped out.此外，我们证明，在某些情况下，加速运动可以显着增强近区域中的探测器相互作用，而使用两个Rydberg原子作为探测器，相互作用能量的可检测到的加速度可以比检测到的相互作用能量的$ 10^5 $乘以检测到的相互作用效果所需的$ 10^5 $。
In a quantum sense, vacuum is not an empty void but full of virtual particles (fields). It may have long-range properties, be altered, and even undergo phase transitions. It is suggested that long-range properties of a quantum vacuum may be probed by distributing matter over a large spatial volume. Here, we study a simplest example of such, i.e., two uniformly accelerated Unruh-DeWitt detectors which are spatially separated, and examine the inter-detector interaction energy arising from the coupling between the detectors and fluctuating fields to see if novel phenomena related to the long-range properties emerge of a vacuum altered by uniformly accelerating two spatially separated detectors through it. Our results show that when the inter-detector separation is much larger than the thermal wavelength of the Unruh thermal bath, the inter-detector interaction displays a completely new behavior, which, as compared with that of the inertial detectors, is surprisingly exclusively acceleration-dependent, signaling a new phase of the vacuum in which its imprint as seen by two inertial observers seems to be completely wiped out. Moreover, we demonstrate that the inter-detector interaction in the near region can be significantly enhanced by the accelerated motion in certain circumstances, and with two Rydberg atoms as the detectors, the acceleration required for an experimentally detectable enhancement of the interaction energy can be $10^5$ times smaller than that required for the detection of the Unruh effect.
