- Nonlinear optics induced current with angular momentum information
- 内容：
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.
