A single generating function encodes both 4D self-dual nonlinear electrodynamics and 2D integrable sigma models, and newly defined gamma flows preserve the root-T Tbar equation across generalized Born-Infeld, logarithmic, q-deformed, and new closed-form theories.
These models can be systematically de- rived through appropriate transformations of the fundamental equation (16) when applied to the CH-function ℓ(τ) =− 1 λ log(1−λτ)

Root-$T\bar{T}$ Flows Unify 4D Duality-Invariant Electrodynamics and 2D Integrable Sigma Models
A single generating function encodes both 4D self-dual nonlinear electrodynamics and 2D integrable sigma models, and newly defined gamma flows preserve the root-T Tbar equation across generalized Born-Infeld, logarithmic, q-deformed, and new closed-form theories.
