Non-perturbative analysis for a massless minimal quantum scalar with in the inflationary de Sitter spacetime
Sourav Bhattacharya, Nitin Joshi
We consider a massless, minimally coupled quantum scalar field theory with an asymmetric self interaction, () in the inflationary de Sitter spacetime…

Cosmological and black hole islands in multi-event horizon spacetimes
Gopal Yadav, Nitin Joshi
In this paper, we have analyzed the information paradox and its resolution using island proposal in Schwarzschild de-Sitter black hole spacetime. First, we study the information pa…

Decoherence and entropy generation in an open quantum scalar-fermion system with Yukawa interaction
Sourav Bhattacharya, Nitin Joshi, Shagun Kaushal
We have studied the decoherence mechanism in a fermion and scalar quantum field theory with the Yukawa interaction in the Minkowski spacetime, using the non-equilibrium effective f…
