The ins and outs of black holes in AdS

Abstract

This work starts by generalizing the traversable wormhole protocol from the thermofield double state black hole to time-shifted thermofield double state black holes and typical pure state black holes. The protocol is dependent on the time-shift and on the state respectively. The traversability of these states is evidence of the smoothness of the black hole horizons of these states. Inspired by these results, we show that the state-dependent construction of the interior of typical state black holes can be simplified using explicit time dependence. This reduces the state dependence to a single parameter.
