    Ignorance is Cheap: From Black Hole Entropy To Energy-Minimizing States In QFT
  • School
    PHYSICS

    In my first talk, I explained why the generalized entropy appears to be a fundamental quantity in quantum gravity. However, the microscopic origins of the generalized entropy is still a mystery in quantum gravity. Within AdS/CFT, where we have access to a non-perturbative boundary description of quantum gravity, it is known that the generalized entropy of quantum extremal surfaces is fundamentally a von Neumann entropy. In this talk, I will explain new results suggesting that the generalized entropy of black holes (more precisely, quantum marginally trapped surfaces) is fundamentally a coarse-grained entropy from the perspective of the bounda ...
