Geometric secret sharing in a model of Hawking radiation PHYSICS We consider a model of microstates of a BTZ black hole in terms of states of a field theory living on an end of the world brane behind the horizon. We take this field theory to have its own holographic dual geometry, which we call the "inception geometry". In this context, we propose a simple model of quantum extremal surfaces as regular RT surfaces in a geometry obtained by gluing the inception geometry (dual to the state of the brane) to the original black hole spacetime along the end of the world brane. We apply this rule to the case when the microstates are entangled with some auxiliary system (modelling Hawking radiation), and explain ho ... 11:00 - 12:00 IPM holography virtual seminar Geometric secret sharing in a model of Hawking radiation School PARTICLES AND ACCELERATORS Abstract: We consider a model of microstates of a BTZ black hole in terms of states of a field theory living on an end of the world brane behind the horizon.
