Description
Stochastic inflation is a fully non-perturbative approach that allows us to study rare, large inhomogeneities generated during inflation. These inhomogeneities are phenomenologically very interesting because they can lead to the formation of primordial black holes, which are a candidate for dark matter. In this talk, after giving a pedagogical introdution to the stochastic approach to inflation, I will explain why such an approach is inherently non-Markovian, which makes its practical implementation highly challenging. I will then present a novel perturbative approach able to tackle these non-Markovian effects.
