Observing light-induced Floquet band gaps in the longitudinal conductivity of graphene

[摘要] Subjecting materials to strong, carefully tuned light pulses are an increasingly popular route to realise novel physics and functionalities for solid-state systems, with one such example being Floquet engineering. Here, the authors propose to employ optical longitudinal conductivity to probe Floquet-Bloch bands, and demonstrate optical controllability of the conductivity of graphene.
