de Sitter invariance of the dS graviton vacuum
Atsushi Higuchi, Donald Marolf, Ian A. Morrison
The two-point function of linearized gravitons on de Sitter space is infrared divergent in the standard transverse traceless synchronous gauge defined by cosmological coordin…

The IR stability of de Sitter QFT: Physical initial conditions
Donald Marolf, Ian A. Morrison
This work uses Lorentz-signature in-in perturbation theory to analyze the late-time behavior of correlators in time-dependent interacting massive scalar field theory in de Sitter s…

On the Equivalence between Euclidean and In-In Formalisms in de Sitter QFT
Atsushi Higuchi, Donald Marolf, Ian A. Morrison
We study the relation between two sets of correlators in interacting quantum field theory on de Sitter space. The first are correlators computed using in-in perturbation theory in…
