Inflationary Decoherence from the Gravitational Floor
C. P. Burgess, R. Holman, Greg Kaplanek
We re-examine the decoherence rate of primordial fluctuations within minimal inflationary models, using only the gravitational interactions required for the underlying fluctuation-…
Cosmic Purity Lost: Perturbative and Resummed Late-Time Inflationary Decoherence
C. P. Burgess, Thomas Colas, R. Holman +2
We compute the rate with which unobserved fields decohere other fields to which they couple, both in flat space and in de Sitter space, for spectator scalar fields prepared in thei…
Open EFTs, IR Effects and Late-Time Resummations: Systematic Corrections in Stochastic Inflation
C. P. Burgess, R. Holman, G. Tasinato
Though simple inflationary models describe the CMB well, their corrections are often plagued by infrared effects that obstruct a reliable calculation of late-time behaviour. We ada…
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…
