Inflation is always semi-classical: Diffusion domination overproduces Primordial Black Holes
Gerasimos Rigopoulos, Ashley Wilkins
We use the Hamilton-Jacobi (H-J) formulation of stochastic inflation to describe the evolution of the inflaton during a period of Ultra-Slow Roll (USR), taking into account the fie…

Coarse-graining in time with the Functional Renormalisation Group: Relaxation in Brownian Motion
Ashley Wilkins, Gerasimos Rigopoulos, Enrico Masoero
We apply the functional Renormalisation Group (fRG) to study relaxation in a stochastic process governed by an overdamped Langevin equation with one degree of freedom, exploiting t…
