Abstract: 

In this talk, we will review some recent results and progress in realizing quantum features of a black hole, using a simplified toy model which is based on postulating an ad hoc Dirichlet brickwall (or a stretched horizon) outside the black hole event horizon. In particular, we will discuss how this toy model yields interesting and perhaps surprising results that mimic certain features of quantum chaos, associated with a Dip-Ramp-Plateau structure for a probe scalar sector propagating in the background. We will further demonstrate that the corresponding normal mode spectrum of the scalar sector displays a rich thermal physics, upon taking the Dirichlet brickwall arbitrarily close to the event horizon. In this limit, the black hole quasi-normal modes also emerge within the analytic structure of the two-point function.
