DESCRIPTION:Felix Haehl (Institute for Advanced Study\, Princeton) \nThe 
 connections between disordered quantum systems (specifically the Sachdev-Y
 e-Kitaev model)\, ensemble averaging\, and two-dimensional dilaton gravity
  underlie much of the recent progress on holography and quantum gravity. W
 hile the SYK model is a spin liquid even at low temperatures\, closely rel
 ated disordered systems exhibit a spin glass phase\, characterized by erg
 odicity breaking and slow dynamics. I will discuss simple spin glass model
 s and some of their properties that are of interest from a gravitationa
 l point of view. I will propose a holographic interpretation of some cruci
 al features that relates to the fragmentation instability of AdS2 towards 
 a geometry with multiple throats. Based on work with Tarek Anous\, Maine C
 hristos\, and Subir Sachdev.\n
