Fundamental relations for anomalous thermoelectric transport coefficients for Weyl semimetals in the non-linear regime
ORAL · Invited
Abstract
Anomalous Hall and Nernst effects in time-reversal-symmetric systems have recently been theoretically discussed in the non-linear regime and have seen some early success in
experiments. By utilizing the role of Berry curvature dipole, we have derived the fundamental mathematical relations between the anomalous electric and thermoelectric transport coefficients in the non-linear regime. Our formulas replace the celebrated Wiedemann-Franz law and Mott relation for anomalous thermoelectric transport coefficients valid only in the linear response regime. In this talk I will discuss these new formulas and show how they can be
experimentally tested in Weyl semimetals.
