A Tail of Eternal Inflation
Timothy Cohen, Daniel Green, Akhil Premkumar
Non-trivial inflaton self-interactions can yield calculable signatures of primordial non-Gaussianity that are measurable in cosmic surveys. Surprisingly, we find that the phase tra…

Regulating loops in de Sitter spacetime
Akhil Premkumar
Perturbative quantum field theory (QFT) calculations in de Sitter space are riddled with contributions that diverge over time. These contributions often arise from loop integrals,…

Stochastic Inflation at NNLO
Timothy Cohen, Daniel Green, Akhil Premkumar +1
Stochastic Inflation is an important framework for understanding the physics of de Sitter space and the phenomenology of inflation. In the leading approximation, this approach resu…
