Generalised Symmetries and Manifest Duality II: Curved Spacetime
Subhroneel Chakrabarti, Arkajyoti Manna, Madhusudhan Raman
We extend the potential-based formulation of self-dual and duality-symmetric gauge theories developed in \cite{Chakrabarti:2025gyt} to curved spacetime. The gravitational coupling…

Generalised Symmetries and Manifest Duality I: Flat Spacetime
Subhroneel Chakrabarti, Arkajyoti Manna, Madhusudhan Raman
We present a novel, manifestly Lorentz-invariant, local, polynomial, and straightforwardly quantisable action for duality-symmetric gauge theories formulated using gauge potentials…

Large deflection scattering, soft radiation and KMOC formalism
Samim Akhtar, Alok Laddha, Arkajyoti Manna +1
KMOC (Kosower, Maybee, and O'Connell) formalism is an approach to analyze classical scattering in gauge theories and gravity using a class of ``inclusive'' observables which can be…
