Fully-relativistic evolution of vacuum tensor inhomogeneities during inflation
Ericka Florio, E. Paul S. Shellard
We present a complete method for the initialisation and extraction of first-order inflationary tensor perturbations for fully relativistic simulations which incorporate gravitation…
Quantitative classicality in cosmological interactions during inflation
Yoann L. Launay, Gerasimos I. Rigopoulos, E. Paul S. Shellard
We examine the classical and quantum evolution of inflationary cosmological perturbations from quantum initial conditions, using the on-shell and off-shell contributions to correla…
Stochastic Inflation in General Relativity
Yoann L. Launay, Gerasimos I. Rigopoulos, E. P. S. Shellard
We provide a formulation of Stochastic Inflation in full general relativity that goes beyond the slow-roll and separate universe approximations. We show how gauge invariant Langevi…
