de Sitter corrections to supertranslation Ward identity and soft graviton theorem
Pratik Chattopadhyay, Divyesh N. Solanki
We study the tree-level scattering of massless scalars followed by an emission of a soft graviton in the small compact region inside the static patch in de Sitter space. We derive…
Perturbative soft graviton theorems in de Sitter spacetime
Divyesh N. Solanki, Pratik Chattopadhyay, Srijit Bhattacharjee
We consider soft graviton scattering for a theory where Einstein's gravity is minimally coupled to a scalar field in the presence of a cosmological constant, i.e. in a background d…
Soft Theorems and Memory Effects at Finite Temperatures
Divyesh N. Solanki, Srijit Bhattacharjee
We study the soft theorems for photons and gravitons at finite temperatures using the thermofield dynamics approach. The soft factors lose universality at finite temperatures as th…
