Exact Relevant Stress-Tensor Flows and a Causality No-Go in Self-Dual Electrodynamics
H. Babaei-Aghbolagh, Bin Chen, Song He +1
Can a classically relevant stress-tensor deformation be exactly solvable, duality preserving, and physically causal? We construct an exact power-law family of nonlinear electrodyna…
