Floquet-Engineered Valleytronics in Dirac Systems
Floquet-Engineered Valleytronics in Dirac Systems
Valley degrees of freedom offer a potential resource for quantum information processing if they can be effectively controlled. We discuss an optical approach to this problem in which intense light breaks electronic symmetries of a two-dimensional Dirac material. The resulting quasienergy structures may then differ for different valleys, so that …
