Reprint of : Probing (topological) Floquet states through DC transport
چکیده انگلیسی


• Periodically driven system can be probed by differential conductances.
• Transport properties and quasi-energy spectrum are indeed related.
• Transport provides an accurate probe of out-of-equilibrium topological edge states.

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.
