Classical conformal invariance and superhorizon dynamics in de Sitter
Maria Cristina Fiore, Andrea F. Sanfilippo
Soft de Sitter Effective Theory is a well-motivated candidate for the correct effective late-time description of equal-time correlation functions in de Sitter space. In this work,…

Quantum correction to the diffusion term in stochastic inflation from composite-operator matching in Soft de Sitter Effective Theory
Martin Beneke, Patrick Hager, Andrea F. Sanfilippo
In the framework of Soft de Sitter Effective Theory (SdSET), the Fokker-Planck equation for the late-time dynamics of the massless minimally coupled scalar field and its extension…

Renormalisation and matching of massless scalar correlation functions in Soft de Sitter Effective Theory
Martin Beneke, Patrick Hager, Andrea F. Sanfilippo
For light and massless scalar fields, cosmological correlation functions suffer from infrared divergences and secular logarithms. Soft de Sitter Effective Theory (SdSET) has been p…
