Physical meaning and consequences of the loop IR divergences in global dS
E. T. Akhmedov
Following arXiv:1012.2107 we show that in global de Sitter space its isometry is broken by the loop IR divergences for any invariant vacuum state of the massive scalars. We derive…

Comparative study of loop contributions in AdS and dS
E. T. Akhmedov, A. V. Sadofyev
The generic feature of non-conformal fields in Poincare patch of de Sitter space is the presence of large IR loop corrections even for massive fields. Moreover, in global de Sitter…

Solution of the Dyson--Schwinger equation on de Sitter background in IR limit
E. T. Akhmedov, Ph. Burda
We propose an ansatz which solves the Dyson-Schwinger equation for the real scalar fields in Poincare patch of de Sitter space in the IR limit. The Dyson-Schwinger equation for thi…
