Stress Tensor flows, birefringence in non-linear electrodynamics and supersymmetry
We identify the unique stress tensor deformation which preserves zero-birefringence conditions in non-linear electrodynamics, which is a $4d$ version of the $T\overline{T}$ operator. We study the flows driven by this operator in the three Lagrangian theories without birefringence - Born-Infeld, Pleb...
