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…
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…
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…
Exploring T-Duality for Self-Dual Fields
Subhroneel Chakrabarti, Madhusudhan Raman
We study avatars of T-duality within Sen's formalism for self-dual field strengths in various dimensions. This formalism is shown to naturally accommodate the T-duality relation be…
