IR flow of stochastic power spectra for interacting spectator scalars in the inflationary de Sitter spacetime
Vishal Nath, Sourav Bhattacharya
In this work we investigate the behaviour of early inflationary cosmic correlation functions under the flow of the infrared scale for interacting spectator scalar field theories. W…
Effect of non-minimal coupling on gravitational light bending
Ayan Kumar Naskar, Avijit Sen Majumder, Sourav Bhattacharya
We investigate the bending of massless fields by a massive object in the presence of a curvature-scalar non-minimal coupling up to one loop, using the perturbativ…
non-minimal coupling, and the long range gravitational potential for different spin fields from 2-2 scattering amplitudes
Avijit Sen Majumder, Ayan Kumar Naskar, Sourav Bhattacharya
In this paper, we investigate the long range gravitational effect of curvature-scalar field non-minimal coupling in the form of , in the perturbative quantum gravity framew…
Yukawa scalar self energy at two loop and in the inflationary de Sitter spacetime
Sourav Bhattacharya, Moutushi Dutta Choudhury
We have considered the Yukawa theory at two loop in the inflationary de Sitter spacetime, for a massless minimally coupled scalar and a massless fermion. The one loop computation f…
