Abstract

Mathur and Mehta won the third prize in the 2023 Gravity Research Foundation Essay Competition for proving the universality of black hole (BH) thermodynamics. Specifically, they demonstrated that any Extremely Compact Object (ECO) must have the same BH thermodynamic properties regardless of whether or not the ECO possesses an event horizon. The result is remarkable, but it was obtained under the approximation according to which the BH emission spectrum has an exactly thermal character. In fact, strong arguments based on energy conservation and BH back reaction imply that the spectrum of the Hawking radiation cannot be exactly thermal. In this work the result of Mathur and Mehta will be extended to the case where the radiation spectrum is not exactly thermal using the concept of BH dynamical state.

量子力学辐射黑洞偏离热力学的普遍性
马图尔和梅塔因证明了黑洞(BH)热力学的普遍性而赢得了2023年引力研究基金会论文竞赛的三等奖。具体地说,他们证明了任何极紧凑天体(ECO)都必须具有相同的黑洞热力学特性,无论该极紧凑天体是否具有事件视界。这一结果非常了不起,但它是在BH发射光谱具有完全热特性的近似条件下获得的。事实上,基于能量守恒和 BH 反作用的有力论证意味着霍金辐射的光谱不可能完全是热的。在这项工作中,马瑟尔和梅塔的研究结果将利用BH动力学状态的概念扩展到辐射谱不完全是热的情况。
