    • Irradiated graphene as a tunable Floquet topological insulator 

      Usaj, Gonzalo; Pérez Piskunow, Pablo Matías; Foa Torres, Luis Eduardo Francisco; Balseiro, Carlos A. (2014)
      In the presence of a circularly polarized mid-infrared radiation graphene develops dynamical band gaps in its quasienergy band structure and becomes a Floquet insulator. Here, we analyze how topologically protected edge ...

    • Multiterminal conductance of a floquet topological insulator 

      Foa Torres, Luis Eduardo Francisco; Pérez Piskunow, Pablo Matías; Balseiro, Carlos A.; Usaj, Gonzalo (2014)
      We report on simulations of the dc conductance and quantum Hall response of a Floquet topological insulator using Floquet scattering theory. Our results reveal that laser-induced edge states lead to quantum Hall plateaus ...
