We consider several models of two entangled 2d black holes in Jackiw-Teitelboim (JT) gravity with negative cosmological constant. The fi rst\, "doubled PSSY\," model is one in which the black holes have end-of-t he-world (ETW) branes with a flavour degree of freedom. We study highly en tangled states of this flavour degree of freedom and find an entanglement- induced Hawking-Page-like transition from a geometry with two disconnected black holes to one with a pair of black holes connected by a wormhole\, t hus realising the ER = EPR proposal. The second model is a dynamical one i n which the ETW branes do not have internal degrees of freedom but the JT gravity is coupled to a 2d CFT\, and we entangle the black holes by coupli ng the two CFTs at the AdS boundary and evolving for a long time. We study the entanglement entropy between the two black holes and find that the st ory is substantially similar to that with a non-gravitating thermal bath. In the third model\, we couple the two ends of a two-sided eternal black h ole and evolve for a long time. Finally\, we discuss the possibility of a Hawking-Page-like transition induced by real-time evolution that realises the ER = EPR proposal in this dynamical setting.\n LOCATION:https://researchseminars.org/talk/qucos/5/ END:VEVENT END:VCALENDAR
