Exact stress-tensor generators distinguish integrable continuations
H. Babaei-Aghbolagh, Song He, Zahra Pezhman
The same leading interaction can coexist with sharply different strong-field responses, even within causal, classically integrable sigma models. We reconstruct exact auto…

Classifying Causal Nonlinear Electrodynamics via -Parity and Irrelevant Deformations
H. Babaei-Aghbolagh, Komeil Babaei Velni, Song He +1
We investigate the classification of self-dual nonlinear electrodynamic (NED) theories based on their analyticity properties, which are directly linked to invariance under a discre…

Root- Deformations on Causal Self-Dual Electrodynamic Theories
Hossein Babaei-Aghbolagh, Komeil Babaei Velni, Song He +1
The self-dual condition, which ensures invariance under electromagnetic duality, manifests as a partial differential equation in nonlinear electromagnetism theories. The general so…
