  • Kibis, Oleg; Dini, Kevin Tanguy Elian; Iorsh, Ivan; Shelykh, Ivan (American Physical Society (APS), 2017-03-01)
    We demonstrate theoretically that the interaction of electrons in gapped Dirac materials (gapped graphene and transition-metal dichalchogenide monolayers) with a strong off-resonant electromagnetic field (dressing field) substantially renormalizes the ...
  • Marques, Y.; Obispo, A. E.; Ricco, L. S.; de Souza, M.; Shelykh, Ivan; Seridonio, A. C (American Physical Society (APS), 2017-07-11)
    The ground state of the diatomic molecules in nature is inevitably bonding, and its first excited state is antibonding. We demonstrate theoretically that, for a pair of distant adatoms placed buried in three-dimensional-Dirac semimetals, this natural ...
  • Whittaker, C. E.; Cancellieri, E.; Walker, P. M.; Gulevich, D. R.; Schomerus, H.; Vaitiekus, D.; Royall, B.; Whittaker, D. M.; Clarke, E.; Iorsh, Ivan; Shelykh, Ivan; Skolnick, M. S.; Krizhanovskii, D. N. (American Physical Society (APS), 2018-03-02)
    We study exciton polaritons in a two-dimensional Lieb lattice of micropillars. The energy spectrum of the system features two flat bands formed from S and P x , y photonic orbitals, into which we trigger bosonic condensation under high power ...
  • 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, ...
  • Gulevich, D. R.; Yudin, D.; Skryabin, D. V.; Iorsh, Ivan; Shelykh, Ivan (Springer Nature, 2017-05-11)
    Matter in nontrivial topological phase possesses unique properties, such as support of unidirectional edge modes on its interface. It is the existence of such modes which is responsible for the wonderful properties of a topological insulator – material ...
  • Pervishko, Anastasiia A.; Yudin, Dmitry; Shelykh, Ivan (American Physical Society (APS), 2018-02-16)
    Lowering of the thickness of a thin-film three-dimensional topological insulator down to a few nanometers results in the gap opening in the spectrum of topologically protected two-dimensional surface states. This phenomenon, which is referred to as the ...
  • Morina, Skender; Dini, Kevin Tanguy Elian; Iorsh, Ivan; Shelykh, Ivan (American Chemical Society (ACS), 2018-02-12)
    We propose an experimentally friendly scheme for trapping quasi-relativistic electrons in graphene by an electromagnetic beam with circular polarization and a spatially inhomogeneous profile with an intensity dip. The trapping is achieved due to the ...
  • Iorsh, Ivan; Dini, Kevin Tanguy Elian; Kibis, Oleg; Shelykh, Ivan (American Physical Society (APS), 2017-10-11)
    It is shown theoretically that the renormalization of the electron energy spectrum of bilayer graphene with a strong high-frequency electromagnetic field (dressing field) results in the Lifshitz transition—the abrupt change in the topology of the Fermi ...
  • Kozin, Valerii; Iorsh, Ivan; Kibis, Oleg; Shelykh, Ivan (American Physical Society (APS), 2018-01-11)
    We demonstrate theoretically that a strong high-frequency circularly polarized electromagnetic field can turn a two-dimensional periodic array of interconnected quantum rings into a topological insulator. The elaborated approach is applicable to calculate ...
  • Kozin, Valerii; Iorsh, Ivan; Kibis, Oleg; Shelykh, Ivan (American Physical Society (APS), 2018-04-26)
    We developed the theory of electronic properties of semiconductor quantum rings with the Rashba spin-orbit interaction irradiated by an off-resonant high-frequency electromagnetic field (dressing field). Within the Floquet theory of periodically driven ...
  • Marques, Y.; Yudin, D.; Shelykh, Ivan; Seridonio, A. C. (American Physical Society (APS), 2018-06-12)
    Recently, it was shown both theoretically and experimentally that certain three-dimensional (3D) materials have Dirac points in the Brillouin zone, thus being 3D analogs of graphene. Moreover, it was suggested that under specific conditions a pair of ...
  • Yulin, A V; Iorsh, Ivan; Shelykh, Ivan (IOP Publishing, 2018-05-31)
    We study the structure of the elementary excitations and their propagation in chiral hybrid structure, comprising an array of two-level systems (TLSs) coupled to a one-dimensional photonic waveguide. The chirality is achieved via spin-locking effect, ...
  • Gulevich, D. R.; Yudin, D.; Skryabin, D. V.; Iorsh, Ivan; Shelykh, Ivan (IEEE, 2017-05)
    We study discrete nonlinear edge excitations of polaritonic kagome lattice. We show that when nontrivial topological phase of polaritons is realized, the kagome lattice permits propagation of bright solitons formed from topological edge states.
  • Kozin, Valerii; Shelykh, Ivan; Nalitov, Anton; Iorsh, Ivan (American Physical Society (APS), 2018-09-10)
    The Chern insulator phase is shown to emerge in two-dimensional arrays of polariton rings where time-reversal symmetry is broken due to the application of an out-of-plane magnetic field. The interplay of Zeeman splitting with the photonic analog of ...
  • Sich, M.; Chana, J. K.; Egorov, O. A.; Sigurdsson, Helgi; Shelykh, Ivan; Skryabin, D. V.; Walker, P. M.; Clarke, E.; Royall, B.; Skolnick, M. S.; Krizhanovskii, D. N. (American Physical Society (APS), 2018-04-19)
    We explore phase transitions of polariton wave packets, first, to a soliton and then to a standing wave polariton condensate in a multimode microwire system, mediated by nonlinear polariton interactions. At low excitation density, we observe ballistic ...
  • Ricco, L. S.; Dessotti, F. A.; Shelykh, Ivan; Figueira, M. S.; Seridonio, A. C. (Springer Nature, 2018-02-12)
    We investigate theoretically thermal and electrical conductances for the system consisting of a quantum dot (QD) connected both to a pair of Majorana fermions residing at the edges of a Kitaev wire and two metallic leads. We demonstrate that both ...
