Resummation of local and non-local scalar self energies via the Schwinger-Dyson equation in de Sitter spacetime
Sourav Bhattacharya, Nitin Joshi, Kinsuk Roy
We consider a massless and minimally coupled self interacting quantum scalar field in the inflationary de Sitter spacetime. The scalar potential is taken to be a hybrid, $V(ϕ)= λϕ^…

Decoherence and entropy generation at one loop in the inflationary de Sitter spacetime for Yukawa interaction
Sourav Bhattacharya, Nitin Joshi
The decoherence mechanism is believed to be possibly connected to the quantum to classical transition of the primordial cosmological perturbations in the early universe. In this pa…
