标题： Quantum ergosphere and brick wall entropy

摘要： 我们重新审视了考虑视界结构后反应效应的黑洞熵“砖墙”模型。 我们通过采用准静态近似下的蒸发度规来实现这一点，在这种情况下，与标准施瓦茨希尔德度规的偏离由一个小的发光因子控制。 后反应的一个效果是创建一个类似能层的区域，该区域自然地抑制了场的划分函数计算中的通常发散。 黑洞发光度设定了这种“量子能层”的宽度。 我们发现了一个有限的视界熵贡献，对于与霍金通量相关的发光度，它与贝肯斯坦-霍金关系惊人地一致。 显示英文摘要

摘要： We revisit the "brick wall" model for black hole entropy taking into account back-reaction effects on the horizon structure. We do so by adopting an evaporating metric in the quasi-static approximation in which departures from the standard Schwarzschild metric are governed by a small luminosity factor. One of the effects of the back-reaction is to create an ergosphere-like region which naturally tames the usual divergence in the calculation of the partition function of the field. The black hole luminosity sets the width of such "quantum ergosphere". We find a finite horizon contribution to the entropy which, for the luminosity associated to the Hawking flux, agrees remarkably well with the Bekenstein-Hawking relation.
