Stochastic Inflation is a regime of Cosmic Inflation in which quantum
fluctuations
dominate over the semi-classical evolution. If triggered, it can
create strong inhomogeneities and, possibly, a multiverse structure with
eternally inflating regions. By reversing time,
Baptiste and Christophe
have developed a new formalism to compute the statistics of these
inhomogeneities and apply it to the flat semi-infinite potential where
stochastic inflation is purely quantum.

In a recent publication,
Chiara, Pierre and
Baptiste, together with Vincent
Vennin,
have developed a novel framework to implement stochastic inflation on
random trees. These trees represent dynamically how different
regions of space grow and gradually become causally disconnected.
