Stochastic scalar-tensor inflation and beyond
Yoann Launay
During cosmological inflation, inhomogeneities arising from quantum vacuum fluctuations are stretched to become super-Hubble and effectively classical. As many scenarios of the ori…
DMAP: A Distribution Map for Text
Tom Kempton, Julia Rozanova, Parameswaran Kamalaruban +5
Large Language Models (LLMs) are a powerful tool for statistical text analysis, with derived sequences of next-token probability distributions offering a wealth of information. Ext…
Stochastic Inflation in Numerical Relativity
Yoann L. Launay, Gerasimos I. Rigopoulos, E. Paul S. Shellard
A set of 3+1 equations for stochastic inflation incorporating all metric and scalar matter degrees of freedom, first presented in previous work, are re-derived in a gauge invariant…
Bunch-Davies initial conditions and non-perturbative inflationary dynamics in Numerical Relativity
Yoann L. Launay, Gerasimos I. Rigopoulos, E. Paul S. Shellard
We show that it is possible to simulate realistic inhomogeneities during cosmological inflation with high precision using {Numerical Relativity}. Stochastic initial conditions are…
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…
