论文摘要
最近的LightWave-STM实验已直接在其内在长度和时间尺度上直接显示了单分子振动的空间和时间分辨率。从理论上讲，我们在这里探讨了在泵探针周期方案中探索的Lightwave-STM中铜 - 苯烷氨酸的电子动力学。金属中心中的自旋轨道相互作用会导致流经分子的电荷的击败，这是泵和探针脉冲之间的延迟时间的函数。分子的准脱位阴离子状态与相关自旋和伪自由度的相互交织动力学之间的干扰是这种现象的关键方面。我们直接在广义主方程方法中直接研究了时域中的动力学。
Recent lightwave-STM experiments have shown space and time resolution of single molecule vibrations directly on their intrinsic length and time scales. We address here theoretically the electronic dynamics of a copper-phthalocynanine in a lightwave-STM, explored within a pump-probe cycle scheme. The spin-orbit interaction in the metallic center induces beatings of the electric charge flowing through the molecule as a function of the delay time between the pump and the probe pulses. Interference between the quasi-degenerate anionic states of the molecule and the intertwined dynamics of the associated spin and pseudospin degrees of freedom are the key aspects of such phenomenon. We study the dynamics directly in the time domain within a generalized master equation approach.
