  • Significance Weyl semimetals are exotic materials with negative electrical magnetoresistance: when an electric and magnetic field are applied in parallel, the induced electrical current increases upon increasing magnetic field strength. This is due to an emergent axial quantum anomaly in Weyl semimetals. We present a universal description of thermoelectric transport in weakly disordered Weyl semimetals where electron–electron interactions are faster than electron–impurity scattering. We predict… CONTINUE READING
