论文摘要
通过光学手段对物质的表征和控制是由于基本见解和技术希望，在研究的最前沿。定期驱动系统的理论建模是理解和工程纳米级量子设备的量子技术的先决条件。在这里，我们在外部周期性驾驶下开发了一种用于分子连接，开放非平衡量子系统的传输和光学响应的理论。使用Floquet理论与系统对系统的功能描述相结合来描述周期性驾驶。使用自洽的天生近似值对光线相互作用进行建模。通用三级模型用于说明驾驶对连接的光学和传输特性的影响。
Characterization and control of matter by optical means is at the forefront of research both due to fundamental insights and technological promise. Theoretical modeling of periodically driven systems is a prerequisite to understanding and engineering nanoscale quantum devices for quantum technologies. Here, we develop a theory for transport and optical response of molecular junctions, open nonequilibrium quantum systems, under external periodic driving. Periodic driving is described using the Floquet theory combined with nonequilibrium Green's function description of the system. Light-matter interaction is modeled employing the self-consistent Born approximation. Generic three-level model is utilized to illustrate effect of the driving on optical and transport properties of junctions.
