DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HET/22/">The
  Page curve for Reflected Entropy</a>\nby Pratik Rath (UCSB) as part of Pu
 rdue HET\n\n\nAbstract\nReflected Entropy is a bipartite correlation measu
 re with a simple geometric holographic dual\, the minimal entanglement wed
 ge cross section. This duality further motivates the idea that spacetime e
 merges from entanglement and illustrates the richness of the multipartite 
 entanglement structure of holographic systems. A particularly interesting 
 feature that we focus on in this talk is the phase transition between a co
 nnected and disconnected entanglement wedge where the reflected entropy ju
 mps discontinuously. We explain how this phase transition is resolved in t
 ensor networks and a model of JT gravity which motivate a general ansatz f
 or the mechanism of the phase transition in AdS/CFT. We also demonstrate h
 ow the reflected entropy calculation motivates a procedure for building up
  geometry using tensor networks.\n
