EFT Beyond the Horizon: Stochastic Inflation and How Primordial Quantum Fluctuations Go Classical
C. P. Burgess, R. Holman, G. Tasinato +1
We identify the effective theory describing inflationary super-Hubble scales and show it to be a special case of effective field theories appropriate to open systems. Open systems…
Inflating with Large Effective Fields
C. P. Burgess, M. Cicoli, F. Quevedo +1
We re-examine large scalar fields within effective field theory, in particular focussing on the issues raised by their use in inflationary models (as suggested by BICEP2 to obtain…
Who You Gonna Call? Runaway Ghosts, Higher Derivatives and Time-Dependence in EFTs
C. P. Burgess, M. Williams
We briefly review the formulation of effective field theories (EFTs) in time-dependent situations, with particular attention paid to their domain of validity. Our main interest is…
Gravitational Forces on a Codimension-2 Brane
C. P. Burgess, L. van Nierop, M. Williams
We compute the gravitational response of six dimensional gauged, chiral supergravity to localized stress energy on one of two space-filling branes, including the effects of compact…
