Causality and energy conditions in nonlinear electrodynamics

# metadata.dc.description.abstract[].value
Abstract: For the general theory of nonlinear electrodynamics (NLED) we prove that causality implies both the Dominant Energy Condition (DEC) and, surprisingly, the Strong Energy Condition (SEC). This has implications for gravitational applications, such as regular black holes supported by NLED matter. For self-dual NLED theories, weak-feld causality alone implies both the DEC and SEC, as we illustrate with Born-Infeld and ModMax electrodynamics.
