(Norm ally) SSC 319 on University Park Campus (USC).\n\nAbstract\nWe extend the holographic duality between 3d pure gravity and the 2d Ising CFT proposed in Ref. [Phys. Rev. D 85 (2012) 024032] to CFTs with boundaries. Besides t he usual asymptotic boundary\, the dual bulk spacetime now has a real cuto ff\, on which live branes with finite tension\, giving Neumann boundary co ndition on the metric tensor. The strongly-coupled bulk theory requires th at we dress the well-known semiclassical AdS/BCFT answer with boundary gra vitons\, turning the partition function into the form of Virasoro characte rs. Using this duality\, we relate the brane tensions to the modular S-mat rix elements of the dual BCFT and derive the transformation between gravit ational solutions with different brane tensions under modular S action.\n\ nYou will enter a waiting room for a short while. Please use your real nam e in your zoom session so that we can distinguish you from random passers- by.\n LOCATION:https://researchseminars.org/talk/USC-HET/13/ END:VEVENT END:VCALENDAR
