    Electron-photonic topological states on the surface of a bulk semiconductor driven by a high-frequency field 
    Kibis, O. V.; Kyriienko, O.; Shelykh, Ivan (IOP Publishing, 2020-03-23)
    It is shown theoretically that the strong coupling of electrons in a bulk gapless semiconductor (HgTe) to a circularly polarized high-frequency electromagnetic field induces topological states on the surface of the semiconductor. Their branches lie ...

    Floquet engineering of 2D materials 
    Kibis, O. V.; Iorsh, I. V.; Shelykh, Ivan (IOP Publishing, 2020-04-23)
    We demonstrate theoretically that the interaction of electrons in the 2D materials (gapped graphene and transition metal dichalchogenide monolayer) with a strong off-resonant electromagnetic field substantially renormalizes their band structure, including ...
