Thermodynamics of quantum fields on rotating black hole spacetimes

Abstract: What is the final quantum state arising from black hole collapse, and what are its thermodynamical properties? In somewhat idealized models like the Kerr metric, the conjectural candidate is the Unruh state. While it is not an equilibrium state, asymptotically one expects the occurrence of Hawking temperature. In this talk I will review recent results that give a rigorous definition and construction based on scattering theory. While the case of bosonic fields on Kerr spacetime is still open, it turns out that it is possible to prove many physical properties of the Unruh state for instance for massless fermions. The talk is based on joint work with Christian Gérard and Dietrich Häfner.
