论文摘要
Lightwave量子电子利用激光场的振荡载体波来控制量子材料的性能。使用量子动力学方程式，我们描述了通过非共线局部自旋的同时量子波动的电子自旋和电荷的灯光驱动的非线性量子转运。在场振荡的周期中，自旋齐荷原子间量子激发触发了抗磁管绝缘子状态的非绝热时间演变，并具有瞬时磁化的金属非平衡状态。电子跳跃的灯波调制改变了能量景观，并建立了具有强烈局部磁交流相关系统中激光诱导的过渡的非热途径。
Lightwave quantum electronics utilizes the oscillating carrier wave of intense laser fields to control quantum materials properties. Using quantum kinetic equations of motion, we describe lightwave-driven nonlinear quantum transport of electronic spin and charge with simultaneous quantum fluctuations of non-collinear local spins. During cycles of field oscillations, spin-charge inter-atomic quantum excitations trigger non-adiabatic time evolution of an antiferromagnetic insulator state into a metallic non-equilibrium state with transient magnetization. Lightwave modulation of electronic hopping changes the energy landscape and establishes a non-thermal pathway to laser-induced transitions in correlated systems with strong local magnetic exchange interactions.
