Kari Enqvist, Janne Hogdahl, Sami Nurmi +1
We present an approach to cosmological perturbations based on a covariant perturbative expansion between two worldlines in the real inhomogeneous universe. As an application, at an…

Scalar condensate decay in a fermionic heat bath in the early universe
K. Enqvist, J. Hogdahl
We consider one-loop thermal effects on the decay of a scalar field zero mode initially dominating the energy density of the universe. We assume fermionic decay channels and take i…
