Description

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. We sketch how this state can be used to compute the stress-energy tensor of the quantum field and present some results of this computation.
