Its conn ection to gravity has implications for understanding bulk reconstruction a nd boundary entanglement. In this talk\, I will further explore this conne ction by studying a regularized version of one-sided modular flow: the Con nes Cocycle (CC) flow. I will define the “kink transform” as a one-sid ed boost of bulk initial data about the Ryu-Takayanagi surface of a bounda ry cut. For a flat cut\, I will demonstrate that the resulting Wheeler-DeW itt patch is the bulk dual to the boundary state obtained by CC flow acros s the cut. I will do so by verifying that the kink transform is consistent with known properties of operator expectation values and subregion entrop ies under CC flow. Moreover\, I will show that CC flow generates a stress tensor shock at the cut\, controlled by a shape derivative of the entropy. I will demonstrate that the kink transform reproduces this shock holograp hically through a gravitational shock. I will also discuss the relationshi p to one-sided modular flow and JLMS.\n LOCATION:https://researchseminars.org/talk/Kadanoff/20/ END:VEVENT END:VCALENDAR
