DESCRIPTION:Gabor Sarosi (CERN)\nThe volume of the interior of a two-sided
  eternal black hole classically grows forever. I will derive a microscopic
  formula for this volume in JT gravity by summing the non-perturbative con
 tribution of higher topologies. These corrections lead to the saturation o
 f the volume of the interior at times exponential in the entropy of the bl
 ack hole. I will connect the microscopic formula for the volume with prope
 rties of a time-averaged density matrix\, in particular with its second Re
 nyi entropy\, which I argue to measure the number of nearly orthogonal sta
 tes visited by time evolution. I will discuss various problems with this i
 nterpretation.\n
