Some aspects of quantum correlations and decoherence in the cosmological spacetimes
Nitin Joshi
This thesis presents a theoretical investigation into the quantum field theoretic aspects of quantum correlations and decoherence in the cosmological spacetimes. We shall focus on…

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^…

Some measures for fermionic entanglement in the cosmological de Sitter spacetime
Sourav Bhattacharya, Himanshu Gaur, Nitin Joshi
We investigate two measures of quantum correlations and entanglement, namely the violation of the Bell-Mermin-Klyshko inequalities and the quantum discord, for Dirac fermions in th…
