Abstract

Atoms falling into a black hole (BH) through a cavity are shown to enable coherent amplification of light quanta powered by the BH-gravitational vacuum energy. This process can harness the BH energy towards useful purposes, such as propelling a spaceship trapped by the BH. The process can occur via transient amplification of a signal field by falling atoms that are partly excited by Hawking radiation reflected by an orbiting mirror. In the steady-state regime of thermally equilibrated atoms that weakly couple to the field, this amplifier constitutes a BH-powered quantum heat engine. The envisaged effects substantiate the thermodynamic approach to BH acceleration radiation.

黑洞供电量子相干放大器

研究表明，原子通过空腔落入黑洞（BH）后，可以利用黑洞引力真空能量对光量子进行相干放大。这一过程可以利用黑洞能量达到有用的目的，例如推动被黑洞困住的飞船。这一过程可以通过下落原子对信号场的瞬态放大来实现，这些原子部分是被轨道镜反射的霍金辐射激发的。在与场弱耦合的热平衡原子的稳态状态下，这种放大器构成了一个由 BH 驱动的量子热引擎。所设想的效应证实了热力学方法对 BH 加速辐射的作用。
