In this talk, I will address (three seemingly unrelated) aspects of quantum black hole physics. The static aspects concern supersymmetric black hole entropy. I will present a modest approach that may shed light on the exact states contributing to single and multi-center black hole entropy; this approach, inspired by the work of Denef-Moore and Manschot-Pioline-Sen, reproduces all the polar states of the corresponding elliptic genera of the microscopic CFTs. I will argue that this is a good starting point to push into the non-polar sector. The dynamical aspects concern the nature of the horizon of non-extremal black holes. Picking up on 't Hooft's ideas on the Black Hole S-Matrix, I will show that the horizon of the Schwarzschild black hole behaves like an inverted harmonic oscillator in quantum mechanics. Time permitting, I will present (soon-to-appear) results on how one may consistently couple large-N CFTs, a gravitational interpretation of the coupled theory and what field theoretic and gravitational lessons we may learn from these.
