    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 ...

    Exciton-exciton interaction in transition-metal dichalcogenide monolayers 
    Shahnazaryan, Vanik; Iorsh, Ivan; Shelykh, Ivan; Kyriienko, O. (American Physical Society (APS), 2017-09-06)
    We study theoretically the Coulomb interaction between excitons in transition metal dichalcogenide (TMD) monolayers. We calculate direct and exchange interaction for both ground and excited states of excitons. The screening of the Coulomb interaction, ...

    Highly nonlinear trion-polaritons in a monolayer semiconductor 
    Emmanuele, R. P. A.; Sich, M.; Kyriienko, O.; Shahnazaryan, V.; Withers, F.; Catanzaro, A.; Walker, P. M.; Benimetskiy, F. A.; Skolnick, M. S.; Tartakovskii, A. I.; Shelykh, Ivan; Krizhanovskiǐ, Dmitry N. (Springer Science and Business Media LLC, 2020-07-17)
    Highly nonlinear optical materials with strong effective photon-photon interactions are required for ultrafast and quantum optical signal processing circuitry. Here we report strong Kerr-like nonlinearities by employing efficient optical transitions ...

    Structure of surface electronic states in strained mercury telluride 
    Kibis, Oleg; Kyriienko, O.; Shelykh, Ivan (IOP Publishing, 2019-04-12)
    We present the theory describing the various surface electronic states arisen from the mixing of conduction and valence bands in a strained mercury telluride (HgTe) bulk material. We demonstrate that the strain-induced band gap in the Brillouin zone ...
