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…
One loop in vs : 4-point check
Aviral Aggarwal, Subhroneel Chakrabarti, Steven Weilong Hsia +2
The one-loop correction to eleven-dimensional supergravity involves a cubically divergent term , with four Riemann tensors. A similar term (with finite coefficient) has…
Perturbative Unitarity Calls for An Action
Subhroneel Chakrabarti, Renann Lipinski Jusinskas
In this work, we investigate the consistency of a perturbative definition of the S-matrix in a particular class of non-Lagrangian theories. We focus on the -form theories propos…
Monopoles, Clarified
Aviral Aggarwal, Subhroneel Chakrabarti, Madhusudhan Raman
We propose a manifestly duality-invariant, Lorentz-invariant, and local action to describe quantum electrodynamics theory in the presence of magnetic monopoles that derives from Se…
