Nonlinear (chiral) p-form electrodynamics

A bstract In our previous article Phys. Rev. Lett. 127 (2021) 271601, we announced a novel ‘democratic’ Lagrangian formulation of general nonlinear electrodynamics in four dimensions that features electric and magnetic potentials on equal footing. Here, give an expanded more detailed account this new formalism, then proceed to push it significantly further by building the corresponding theories higher form field interactions arbitrary dimensions. Special attention is given chiral 2 k -forms 4 + dimensions, with details for 2-forms 6 4-forms 10 We comment broadly structure covariant equations motion fields, place context. The develop are simple explicit, cover much broader class than all past attempts literature.
