Small noise expansion of stochastic inflation
Diego Cruces, Cristiano Germani, Amin Nassiri-Rad +1
By introducing the small noise expansion techniques, we show that the fully nonlinear (non-Markovian) stochastic inflationary system, may be re-cast in terms of an infinite set of…
An update on adiabatic modes in cosmology and N formalism
Diego Cruces, Cristiano Germani, Adrian Palomares
In this paper, we generalize the Weinberg's procedure to determine the comoving curvature perturbation to non-attractor inflationary regimes. We show that both modes of $\…
Stochastic inflation at all order in slow-roll parameters: foundations
Diego Cruces, Cristiano Germani
In this paper we develop the formalism for the stochastic approach to inflation at all order in slow-roll parameters. This is done by including the momentum and Hamiltonian constra…
Failure of the stochastic approach to inflation beyond slow-roll
Diego Cruces, Cristiano Germani, Tomislav Prokopec
After giving a pedagogical review we clarify that the stochastic approach to inflation is generically reliable only at zeroth order in the (geometrical) slow-roll parameter i…
