A consistent formulation of stochastic inflation I: Non-Markovian effects and issues beyond linear perturbations
Diego Cruces, Tomotaka Kuroda
We investigate the origin of non-Markovianity in stochastic inflation and its implications for nonlinear perturbation theory. In the Schwinger--Keldysh formulation, the noise terms…
Natura Non Facit Saltum: An Analytical Model of Smooth Slow-Roll to Ultra-Slow-Roll Transition
Diego Cruces, Minxi He, Shi Pi +3
In this letter, we propose a single-field inflation model that realizes a slow-roll-to-ultra-slow-roll transition while keeping the second slow-roll parameter smoothly varying thro…
formalism: A new formulation for the probability density of the curvature perturbation
Diego Cruces, Shi Pi, Misao Sasaki
formalism is a useful method to calculate the curvature perturbation. Contrary to what it is typically done in the literature, we re-formulate the formalism by using the…
Review on stochastic approach to inflation
Diego Cruces
We present a review on the state-of-the-art of the mathematical framework known as stochastic inflation, paying special attention to its derivation and giving references for the re…
