    Exciton Polaritons in a Two-Dimensional Lieb Lattice with Spin-Orbit Coupling 
    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 ...

    Exploring nonlinear topological states of matter with exciton-polaritons: Edge solitons in kagome lattice 
    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 ...

    Stability and lifetime of antiferromagnetic skyrmions 
    Bessarab, Pavel; Yudin, D.; Gulevich, D. R.; Wadley, P.; Titov, M.; Tretiakov, Oleg A. (American Physical Society (APS), 2019-04-26)
    The two-dimensional Heisenberg exchange model with out-of-plane anisotropy and a Dzyaloshinskii-Moriya interaction is employed to investigate the lifetime and stability of antiferromagnetic (AFM) skyrmion as a function of temperature and external ...

    Topological edge solitons in polaritonic lattice 
    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.
