"A classical computation of (pre)Hawking radiation backreaction" |

In this talk I will discuss how a gravitationally collapsing object emits classical radiation at a rate equal to the quantum radiation rate if suitable initial conditions are chosen for two classical fields. The coupled dynamics of gravitational collapse and radiation are then solved for in a simple toy model, illustrating how the classical system may be used to gain insight into Hawking evaporation. |
