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…

The Triple -Like Flow in Quantum Field Theories: Irrelevant, Marginal, and Relevant
H. Babaei-Aghbolagh, Bin Chen, Song He +1
We introduce a one-parameter root--like flow, , which organizes stress-tensor deformations into irrelevant, marginal, and re…

Self-Dual Electrodynamics via the Characteristic Method: Relativistic and Carrollian Perspectives
Bin Chen, Song He, Jue Hou
Electric-magnetic duality plays a pivotal role in understanding the structure of nonlinear electrodynamics (NED). The Gaillard-Zumino (GZ) criterion provides a powerful constraint…
