Dynamically Driven Systems: The case of Graphene

Topological insulators are an exotic family of materials where a bulk gap is bridged by surface states which propagate even in the presence of disorder In some materials the non trivial topological properties are crafted with an external driving e g a circularly polarized laser these new state of matter is known as b Floquet topological insulatorsb In the case of grapheme radiation may create bulk band gaps transforming the system into a two dimensional Floquet topological insulator I will discuss th
