This letter is organised as follows. In section 2 we demonstrate that our formulation (1.9) generates self-dual NLED theories satisfying strong causality conditions. We also review the Courant-Hilbert solution for self-dual NLED [4,7] and discuss the interplay betweenU(1) duality invariance and the causal structure of NLED theories. Section 3 demonstrates the generality of our formulation. Concluding comments are given in section 4. Appendix A is devoted to the technical aspect of non-recoverability of seed theory. 2 Causality and self-duality In this section we demonstrate that our auxiliary-field formulation (1."},{"citing_arxiv_id":"2605.03018","ref_index":39,"ref_count":1,"confidence":0.9,"is_internal_anchor":false,"paper_title":"Gravitational electric-magnetic duality at the light ring and quasinormal mode isospectrality in effective field theories","primary_cat":"gr-qc","submitted_at":"2026-05-04T18:00:10+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":7.0,"formal_verification":"none","one_line_summary":"Gravitational electric-magnetic duality at the light ring organizes and preserves quasinormal mode isospectrality in GR and selects duality-invariant higher-derivative corrections in effective field theories.","context_count":1,"top_context_role":"background","top_context_polarity":"background","context_text":"Lett. 134, 191401 (2025), arXiv:2407.12080 [hep-th].
