Nonperturbative Floquet-Keldysh theory for SHG in two-band systems predicts a shift from E squared to linear E scaling then to field-independent response, controlled by one- and two-photon resonances, and verified numerically in a GeS model.
Extends density-matrix kinetic theory beyond non-crossing approximation to fourth-order disorder, yielding extrinsic tau^0 contributions to anomalous Hall conductivity in the 2D Dirac model.
