Dynamics driven by the Trace Anomaly in FLRW Universes
J. F. Koksma
By means of a semiclassical analysis we show that the trace anomaly does not affect the cosmological constant. We calculate the evolution of the Hubble parameter in quasi de Sitter…

Decoherence in an Interacting Quantum Field Theory: The Vacuum Case
Jurjen F. Koksma, Tomislav Prokopec, Michael G. Schmidt
We apply the decoherence formalism to an interacting scalar field theory. In the spirit of the decoherence literature, we consider a "system field" and an "environment field" that…

Fermion Propagator in Cosmological Spaces with Constant Deceleration
Jurjen F. Koksma, Tomislav Prokopec
We calculate the fermion propagator in FLRW spacetimes with constant deceleration , for excited states. For fermions whose mass is generated by a scalar f…
