Gravity seminar - Benjamin Berczi  Seminar

Abstract: The behaviour of quantum fields around black holes has been in the forefront of research for almost half a century, since the discovery of Hawking radiation in 1974. However, we still know remarkably little about the details of the evaporation of black holes beyond first order approximations. My talk will introduce our novel formalism using which a fully quantum mechanical field can be simulated to collapse into a black hole, and discuss how the quantum effects can be studied. It is explained how we relate the semiclassical simulations to purely classical ones using a coherent state as the chosen quantum state. Initial results of the quantum effects around the formed black hole will be presented as well.
