*“Black(ish) Holes**"*
*
*
_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.
