量子场与旋转热浴的相互作用

Interaction of a quantum field with a rotating heat bath

Robert Alicki, Alejandro Jenkins

摘要:

在非幺正时间演化的马尔可夫主方程框架下,研究了旋转热浴与量子场的线性耦合。浴的旋转诱导粒子数反转的领域的低能量模式。对于玻色子来说,这会导致超辐射,这是一个不可逆的过程,其中一些浴的动能通过自发发射和受激发射被提取。我们找到了这种系统的能量和熵平衡,并将我们的结果应用到黑洞辐射理论中。我们还评论如何这涉及到经典的自振荡,包括流体力学中的剪切流不稳定性。

英文摘要:

The linear coupling of a rotating heat bath to a quantum field is studied in the framework of the Markovian master equation for the field's non-unitary time evolution. The bath's rotation induces population inversion for the field's low-energy modes. For bosons, this leads to superradiance, an irreversible process in which some of the bath's kinetic energy is extracted by spontaneous and stimulated emission. We find the energy and entropy balance for such systems and apply our results to the theory of black hole radiation. We also comment on how this relates to classical self-oscillations, including shear flow instabilities in hydrodynamics.
