AI中文摘要:
我们推导了晶体中由能带扭转增强的电子非线性颤动速度。包含多态量子几何张量和扭转的运动方程最终产生了瞬态非线性光电流响应,这与最近测量的由圆偏振光诱导的共振稳态光伏效应不同。我们提出了用于测量多态量子几何扭转张量的层析成像协议。
英文摘要:
We derive nonlinear Zitterbewegung velocity of electrons augmented by band torsion in crystals. The equation of motion with multistate quantum geometric tensors and torsion culminates in transient nonlinear photocurrent responses distinct from the recently measured resonant steady-state photovoltaic effects induced by circularly polarized light. Tomography protocols for measuring the multistate quantum geometric torsion tensors are proposed.
