Field-theoretic approach to large-scale structure formation
Pavel Friedrich, Tomislav Prokopec
We develop a field-theoretic description of large-scale structure formation by taking the non-relativistic limit of a canonically transformed, real scalar field which is minimally…

Entropy production in inflation from spectator loops
Pavel Friedrich, Tomislav Prokopec
Perturbations in cosmic microwave background (CMB) photons and large scale structure of the universe are sourced primarily by the curvature perturbation which is widely believed to…

Kinetic theory and classical limit for real scalar quantum field in curved space-time
Pavel Friedrich, Tomislav Prokopec
Starting from a real scalar quantum field theory with quartic self-interactions and non-minimal coupling to classical gravity, we define four equal-time, spatially covariant phase-…
