25. In Ref. the authors claim that fermionic anisotropy goes to one, and thus they obtain the simplified model we used to show that this can be thought as a model in which there are anisotropic couplings in the Maxwellian term. Given that the number of fermions in physical systems is modest it would be interesting to analyze the consequences of having such anisotropic couplings.
