Nonlinear optics induced current with angular momentum information
We apply Kubo perturbation theory and show that pure and hidden orbital current exists in 2D ferroelectrics, and it would trigger spin current under spin-orbit coupling interaction. Symmetry analysis has been applied to understand such pure angular momentum currents.
