Light-induced charge and spin Hall currents in materials with C 4 K symmetry
Abstract Berry curvature can manifest itself in current responses. It has recently been shown that a Berry-curvature quadrupole induces a third-order ac Hall response in systems that break time reversal (K) and a fourfold rotational (C 4) symmetries, while remaining invariant under their combination...
