摘要： 我们考虑一个与无限电极连接的周期驱动系统的微分电导。 我们关注耗散主要发生在这些电极的情况。 通过分析论证和详细数值研究，我们将这种系统在二维和三维端子几何结构中的微分电导与Floquet算符的准能量谱联系起来。 此外，这些微分电导被发现能准确探测准能量谱中间隙的存在，在这些间隙中出现拓扑边缘态时，它们是量子化的。 我们的分析为描述驱动介观导体的中间时间动力学作为拓扑Floquet滤波器提供了前景。 显示英文摘要

摘要： We consider the differential conductance of a periodically driven system connected to infinite electrodes. We focus on the situation where the dissipation occurs predominantly in these electrodes. Using analytical arguments and a detailed numerical study we relate the differential conductances of such a system in two and three terminal geometries to the spectrum of quasi-energies of the Floquet operator. Moreover these differential conductances are found to provide an accurate probe of the existence of gaps in this quasi-energy spectrum, being quantized when topological edge states occur within these gaps. Our analysis opens the perspective to describe the intermediate time dynamics of driven mesoscopic conductors as topological Floquet filters.
