A new unconventional thermoelectric transport in type-I Weyl semimetals
ORAL
Abstract
We analyze the effect of the tilt vector on the transverse thermoelectric coefficient of Weyl semimetals in the conformal limit. We find a non-monotonic behavior of the thermoelectric conductivity as a function of the tilt perpendicular to the magnetic field, and a linear behavior when the tilt is aligned to the magnetic field. An axial Nernst current is also generated in inversion symmetric Weyl materials when the tilt vector has a projection in the direction of the magnetic field.
