Cosmological de Sitter Solutions of the Semiclassical Einstein Equation
Hanno Gottschalk, Nicolai Rothe, Daniel Siemssen
Exponentially expanding space-times play a central role in contemporary cosmology, most importantly in the theory of inflation and in the Dark Energy driven expansion in the late u…
Special cosmological models derived from the semiclassical Einstein equation on flat FLRW space-times
Hanno Gottschalk, Nicolai Rothe, Daniel Siemssen
This article presents numerical work on a special case of the cosmological semiclassical Einstein equation (SCE). The SCE describes the interaction of relativistic quantum matter b…
Scale-Invariant Curvature Fluctuations from an Extended Semiclassical Gravity
Nicola Pinamonti, Daniel Siemssen
We present an extension of the semiclassical Einstein equations which couples n-point correlation functions of a stochastic Einstein tensor to the n-point functions of the quantum…
Hadamard States for the Vector Potential on Asymptotically Flat Spacetimes
Claudio Dappiaggi, Daniel Siemssen
We develop a quantization scheme for the vector potential on globally hyperbolic spacetimes which realizes it as a locally covariant conformal quantum field theory. This result all…
