标题： A Massless Firewall

摘要： 如果接受半经典理论的提示，即在强引力区域，真空的能量密度可能变得显著为负，那么黑洞热力学的几个异常现象就可以得到解决。 这导致了视界作为高温无质量壳层的图像。 从局部(Boulware)基态来看，表观视界是大量能量的储存地，这些能量是热的。 但是，作为引力源，它的质量接近于零。 一个简单的(1+1)维模型提供了这一图像的具体实现。 显示英文摘要

摘要： Several anomalies of black hole thermodynamics are resolved if one accepts hints from semi classical theory that in regions of strong gravity the energy density of the vacuum can become substantially negative. This leads to a picture of the horizon as a hot massless shell. As viewed in the local (Boulware) ground state, the apparent horizon is the repository of a large store of energy, and this energy is thermal. But, as a source of gravity, its mass is near zero. A simple (1+1)-dimensional model provides a concrete realization of this picture.
