  • Wang, Y. H.; Steinberg, Hadar; Jarillo-Herrero, Pablo; Gedik, Nuh (2013-10)
    The unique electronic properties of the surface electrons in a topological insulator are protected by time-reversal symmetry. Circularly polarized light naturally breaks time-reversal symmetry, which may lead to an exotic ...
