Descripción

Weyl and Dirac semimetals are topologically nontrivial metallic systems. Many transport and optical properties of these systems display signatures of their nontrivial topological nature, even being dissipative. Here we will demonstrate that Weyl semimetals display a rather exotic response called "magnetochiral effect" appearing in chiral systems under the effect of external magnetic fields. moreover, we will show how the magnetochiral effect shows up in Weyl semimetals in the linear regime in transport quantities, contrary to all the previously cases found in the literature, where the magnetochiral effect appear in the non-linear regime.
