Consequences of time-reversal-symmetry breaking in the light-matter interaction: Berry curvature, quantum metric, and diabatic motion
Tobias Holder, Daniel Kaplan, Binghai Yan
Abstract
This work generalizes the theory of nonlinear optical response in terms of the anomalous acceleration of the electronic quasiparticle, thus making the physical origin of the semiclassical contributions and the shift and injection currents transparent for materials with broken time-reversal symmetry.
