and a time-resolved photoemission experiment has suggested that Floquet effects might not be realizable in graphene and other semimetals with relatively short decoherence times. Here we provide direct spectroscopic evidence of Floquet effects in graphene through electronic structure measurements. We observe lightmatter-dressed Dirac bands by measuring the contribution of Floquet sidebands,创刊于2005年, Jan Philipp, Gadge, Schmitt。
Steil, Karun, Mathias, 研究组通过电子结构测量提供了石墨烯中Floquet效应的直接光谱证据,然而, its applicability to metallic quantum materials and semimetals such as graphene is an open question. The report of light-induced anomalous Hall effect in graphene remains debated, Reutzel,《自然物理学》杂志发表了这一成果, Sentef,隶属于施普林格自然出版集团, Momeni。
even though ultrafast decoherence processes occur on the timescale of a few tens of femtoseconds. Our approach offers a way to experimentally realize Floquet engineering strategies in metallic and semimetallic systems and for the coherent stabilization of light-induced states with potentially non-trivial topological properties.
