我们回顾的方式BTZ黑洞放松回到热平衡后,一个小的扰动,以及它是如何看到在边界(有限体积)CFT。幺正性要求弛豫是准周期的。它是保存在CFT,但不明显的情况下,半经典黑洞的弛豫是由复杂的准正常模式。我们讨论了两种方法修改半经典黑洞的几何形状,以保持统一性:(分形)砖墙和虫洞修改。在后一种情况下,熵也是正确的。
We review the way the BTZ black hole relaxes back to thermal equilibrium after a small perturbation and how it is seen in the boundary (finite volume) CFT. The unitarity requires the relaxation to be quasi-periodic. It is preserved in the CFT but is not obvious in the case of the semiclassical black hole the relaxation of which is driven by complex quasi-normal modes. We discuss two ways of modifying the semiclassical black hole geometry to maintain unitarity: the (fractal) brick wall and the worm-hole modification. In the latter case the entropy comes out correctly as well.
