Multifield inflation beyond : non-Gaussianities and single-field effective theory
Lucas Pinol
In this article, we study in detail the linear dynamics and cubic interactions for any number of scalar fields during inflation, directly in terms of the observa…

A manifestly covariant theory of multifield stochastic inflation in phase space: solving the discretisation ambiguity in stochastic inflation
Lucas Pinol, Sébastien Renaux-Petel, Yuichiro Tada
Stochastic inflation is an effective theory describing the super-Hubble, coarse-grained, scalar fields driving inflation, by a set of Langevin equations. We previously highlighted…

Metric preheating and radiative decay in single-field inflation
Jérôme Martin, Theodoros Papanikolaou, Lucas Pinol +1
At the end of inflation, the inflaton oscillates at the bottom of its potential and these oscillations trigger a parametric instability for scalar fluctuations with wavelength …
