摘要：
采用量子光学方法研究加速度辐射的性质，该辐射源于一团随机原子云自由落入广义史瓦西黑洞并穿过Boulware真空。通过一个以多模形式完整建立的主方程，分析了这种视界增亮的加速度辐射（HBAR）的性质。考虑了对原子云进行粗粒化平均的方案，重点讨论了随机注入情形，并证明该情形会产生热态。研究表明，共形量子力学（CQM）所起的作用对于通过由近视界物理支配的玻尔兹曼因子实现细致平衡至关重要，并唯一地选择了霍金温度。HBAR热态构成了一个与黑洞热力学相平行的热力学框架的基础。
英文摘要：
A quantum-optics approach is used to study the nature of the acceleration radiation due to a random atomic cloud falling freely into a generalized Schwarzschild black hole through a Boulware vacuum. The properties of this horizon brightened acceleration radiation (HBAR) are analyzed with a master equation that is fully developed in a multimode format. A scheme for the coarse-graining average for an atomic cloud is considered, with emphasis on the random injection scenario, which is shown to generate a thermal state. The role played by conformal quantum mechanics (CQM) is shown to be critical for detailed balance via a Boltzmann factor governed by the near-horizon physics, with the unique selection of the Hawking temperature. The HBAR thermal state is the basis for a thermodynamic framework that parallels black hole thermodynamics.
