论文摘要
我们指出，用于蒸发黑孔的二维Russo-susskind-thorlacius（RST）模型在局部是局部等效的 - 在完整的量子水平上，到最近显示为单位的平面空间jackiw-teitelboim（JT）重力。在全球范围内，这两个模型因第一个模型中添加的反射时空边界而有所不同。将边界视为量子JT理论的局部和协变量的变形，我们开发了对蒸发的第一个黑洞的明智的半经典描述。然而，我们的半经典解决方案无法解决信息恢复问题，并且并不表示残留物的形成。这意味着标准的半经典方法错误地描述了蒸发过程，或者第一个边界使平整空间JT模型从根本上不一致。
We point out that two-dimensional Russo-Susskind-Thorlacius (RST) model for evaporating black holes is locally equivalent - at the full quantum level - to flat-space Jackiw-Teitelboim (JT) gravity that was recently shown to be unitary. Globally, the two models differ by a reflective spacetime boundary added in the RST model. Treating the boundary as a local and covariant deformation of quantum JT theory, we develop sensible semiclassical description of evaporating RST black holes. Nevertheless, our semiclassical solutions fail to resolve the information recovery problem, and they do not indicate formation of remnants. This means that either the standard semiclassical method incorrectly describes the evaporation process or the RST boundary makes the flat-space JT model fundamentally inconsistent.
