Probing quantum criticality using nonlinear Hall effect in a metallic Dirac system
Habib Rostami, Vladimir Juričić
Abstract
This article puts forward a nonlinear spectroscopy technique to probe inversion symmetry breaking in time-reversal symmetric Dirac metals. The authors show that the nonlinear Hall effect features strong interband resonances with a non-Lorentzian profile, which represent its hallmark feature, and are controlled by the tilt parameter.
