Floquet chiral edge states in graphene
Pérez Piskunow, Pablo Matías; Usaj, Gonzalo; Balseiro, Carlos A.; Foa Torres, Luis Eduardo Francisco (2014)We report on the emergence of laser-induced chiral edge states in graphene ribbons. Insights on the nature of these Floquet states is provided by an analytical solution which is complemented with numerical simulations of ... -
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 ...
