Construction of the Unruh state on Kerr-de Sitter

Talk by Dr. Christiane Klein

Date: 20.10.22  Time: 16.00 - 18.00  Room: KOL G209

In order to study physical effects of quantum fields on curved spacetimes, one needs appropriate Hadamard states to describe the fields. In this talk, we present a rigorous construction, including the proof of the Hadamard property, of the Unruh state for the free scalar field on slowly rotating Kerr-de Sitter spacetimes.
