Approximate KMS states for scalar and spinor fields in Friedmann-Robertson-Walker spacetimes
Claudio Dappiaggi, Thomas-Paul Hack, Nicola Pinamonti
We construct and discuss Hadamard states for both scalar and Dirac spinor fields in a large class of spatially flat Friedmann-Robertson-Walker spacetimes characterised by an initia…

On the Backreaction of Scalar and Spinor Quantum Fields in Curved Spacetimes - From the Basic Foundations to Cosmological Applications
Thomas-Paul Hack
First, the present work is concerned with generalising constructions and results in quantum field theory on curved spacetimes from the well-known case of the Klein-Gordon field to…

Dark Energy from Quantum Matter
Claudio Dappiaggi, Thomas-Paul Hack, Jan Möller +1
We study the backreaction of free quantum fields on a flat Robertson-Walker spacetime. Apart from renormalization freedom, the vacuum energy receives contributions from both the tr…
