Abstract: We use Functional Renormalisation Group (FRG) techniques to analyse the behaviour of a spectator field, σ, during inflation that obeys an overdamped Langevin equation. We briefly review how a derivative expansion of the FRG can… read more here.

Abstract: The Kardar–Parisi–Zhang (KPZ) equation is a celebrated non-linear stochastic equation featuring non-equilibrium scaling. Although its statistical properties are well understood in one dimension, a new scaling regime has been reported in recent numerical simulations. This… read more here.
