Cosmological cutting rules for Bogoliubov initial states
Diptimoy Ghosh, Enrico Pajer, Farman Ullah
The field theoretic wavefunction in cosmological spacetimes has received much attention as a fundamental object underlying the generation of primordial perturbations in our univers…
Bispectrum at 1-loop in the Effective Field Theory of Inflation
Supritha Bhowmick, Diptimoy Ghosh, Farman Ullah
In this paper we compute 1-loop corrections to the bispectrum in the decoupling limit of the Effective Field Theory of Inflation (EFToI). We regulate the divergences by employing d…
Inflationary non-Gaussianities in alpha vacua and consistency with conformal symmetries
Arhum Ansari, Pinak Banerjee, Prateksh Dhivakar +2
We study the conformal invariance of inflationary non-Gaussianities associated with scalar fluctuations in a non-Bunch-Davies initial state, known as the -vacuum, in single-fiel…
