What is Weyl Geometry in Weyl Semimetals about?

A novel oscillatory behaviour of the DC conductivity in Weyl semimetals with vacancies has recently been identified, occurring in the absence of external magnetic fields. Here, we argue that this effect has a geometric interpretation in terms of a magnetic-like field induced by an emergent Weyl connection. This geometric gauge field is related to the non-metricity of the underlying effective geometry, which is physically induced by vacancies in the lattice system. Finally, we postulate that the chiral magnetic effect in Weyl semimetals can be affected by the presence of dynamical vacancies.
