Abstract
Born's original 1933 theory of nonlinear electrodynamics (in contrast to the later Born-Infeld theory) is acausal for strong fields. We explore the issue of strong-field causality violation in families of theories containing Born and/or Born-Infeld, and many variants that have been previously proposed in contexts that include cosmology and black hole physics. Many of these variants are acausal and hence unphysical. A notable exception is the modified Born-Infeld theory with ModMax as its conformal weak-field limit.

Report
This manuscript describes the results of a very deep and interesting study of the causality in nonlinear electrodynamics models, especially in their strong field limits. In particular, the Born model, processor of the Born-Infeld theory is addressed. This happen to be acausal like many other models discussed in the context of black hole physics and cosmology. The special properties of the modified Born-Infeld theory which has recently found ModMax model as a conformal limit are emphasised.

Strengths
This is an interesting paper that gives a nice review of non-linear electrodynamics and provides a classification of models that preserve causality.
The authors stress importance of identifying strong-field causality violations in applications of nonlinear electrodynamics models with possible applications to strong field phenomena in the context of gravity theories where one is to avoid
acausal propagation.
Report
the paper meets publication criteria (see above)
