The Asymptotic Structure of Gravity in Higher Even Dimensions
Chandramouli Chowdhury, Ruchira Mishra, Siddharth G. Prabhu
We investigate the notion of asymptotic symmetries in classical gravity in higher even dimensions, with space-time dimensions as the prototype. Unlike in four dimensions, c…
On loop celestial amplitudes for gauge theory and gravity
Soner Albayrak, Chandramouli Chowdhury, Savan Kharel
Scattering amplitudes of massless particles in Minkowski space can be expressed in a conformal basis by Mellin transforming the momentum space amplitudes to correlation functions o…
An étude of momentum space scalar amplitudes in AdS
Soner Albayrak, Chandramouli Chowdhury, Savan Kharel
In this paper, we explore momentum space approach to computing scalar amplitudes in Anti-de Sitter space. We show that the algorithm derived by Arkani-Hamed, Benincasa, and Postnik…
New relation for AdS amplitudes
Soner Albayrak, Chandramouli Chowdhury, Savan Kharel
In this paper, we present a simple and iterative algorithm that computes Anti-de Sitter space scattering amplitudes. We focus on the vector correlators in AdS in four dimensions in…
How robust is the indistinguishability between quantum fluctuation seen from non-inertial frame and real thermal bath
Chandramouli Chowdhury, Susmita Das, Surojit Dalui +1
We re-advocated the conjecture of indistinguishability between the quantum fluctuation observed from a Rindler frame and a real thermal bath, for the case of a free massless scalar…
Conformal Vacuum and Fluctuation-Dissipation in de-Sitter Universe and Black Hole Spacetimes
Ashmita Das, Surojit Dalui, Chandramouli Chowdhury +1
In the studies of quantum field theory in curved spacetime, the ambiguous concept of vacuum state and the particle content is a long-standing debatable aspect. So far it is well kn…
