Detection of quantum geometric tensor by nonlinear optical response
Zhi Li, Takami Tohyama, Toshiaki Iitaka +2
Quantum geometric tensor (QGT), including a symmetric real part defined as quantum metric and an antisymmetric part defined as Berry curvature, is essential for understanding many…

Nonlinear optical response from quantum kinetic equation
Zhi Li, Takami Tohyama, Toshiaki Iitaka +2
Motivated by the nonlinear Hall effect observed in topological semimetals, we studied the photocurrent by the quantum kinetic equation. We recovered the shift current and injection…
