String Theory seminar - Ramy Brustein Seminar

Hawking has discovered more than 40 years ago that black holes (BH’s) evaporate. Ever since, ideas about how they evaporate have been a source of constant interest and controversy. In recent years we are witnessing a paradigm shift: from asking whether BH’s evaporation respects the laws of quantum mechanics to finding what is the quantum state of the BH and what are its physical properties. I will propose that the quantum state of BH interior is a highly quantum bound state and present a model for this maximally entropic state. The proposal relies on the observation that the state of the radiation emitted from a finite mass BH is highly quantum.
