In Lorentz violating quantum electrodynamics (QED) it is known that a radiatively induced Chern-Simons term appears in the effective action for the gauge field, which is finite but undetermined. This ambiguity is shown to be absent in a condensed matter realization of such a theory in Weyl semi-metals due to the existence of a full microscopic model from which this effective theory emerges. Physically observable consequences such as birefringence are also discussed in this scenario.

Materials perspective on Casimir and van der Waals interactions (2015, background): “Recent reports show that the quantum electrodynamics in Weyl semimetals results in a non-trivial response due to the associated axion field, which can lead to a repulsive Casimir interaction (Grushin, 2012; Wilson et al., 2015).”
