Dualities of self-dual nonlinear electrodynamics Russo, J. G. (Jorge Guillermo) Townsend, Paul K. Electrodinàmica Camps de galga (Física) Electrodynamics Gauge fields (Physics) For any causal nonlinear electrodynamics theory that is “self-dual” (electromagnetic U(1)-duality invariant), the Legendre-dual pair of Lagrangian and Hamiltonian densities {L, H} are constructed from functions {ℓ, h} on R + related to a particle-mechanics Lagrangian and Hamiltonian. We show how a ‘duality’ relating ℓ to h implies that L and H are related by a simple map between appropriate pairs of variables. We also discuss Born’s “Legendre self-duality” and implications of a new “Φ-parity” duality. Our results are illustrated with many examples.  2025-06-02T16:32:07Z 2025-06-02T16:32:07Z 2024 2025-06-02T16:32:07Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1126-6708 https://hdl.handle.net/2445/221320 757112 eng Reproducció del document publicat a: https://doi.org/10.1007/JHEP09(2024)107 Journal of High Energy Physics, 2024, vol. 2024, num.107 https://doi.org/10.1007/JHEP09(2024)107 cc-by (c) Russo, J.G. et al., 2024 http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess 41 p. application/pdf Springer Verlag Articles publicats en revistes (Física Quàntica i Astrofísica)
