Renormalisation group improvement in the stochastic formalism
Robert J. Hardwick, Tommi Markkanen, Sami Nurmi
We investigate compatibility between the stochastic infrared (IR) resummation of light test fields on inflationary spacetimes and renormalisation group running of the ultra-violet…

Decoherence Can Relax Cosmic Acceleration
Tommi Markkanen
In this work we investigate the semi-classical backreaction for a quantised conformal scalar field and classical vacuum energy. In contrast to the usual approximation of a closed s…

A Simple Method for One-Loop Renormalization in Curved Space-Time
Tommi Markkanen, Anders Tranberg
We present a simple method for deriving the renormalization counterterms from the components of the energy-momentum tensor in curved space-time. This method allows full control ove…
