    A connection between R-invariants and Yang-Baxter R-operators in N$$ \mathcal{N} $$ = 4 super-Yang-Mills theory 
    Kozin, Valerii (Springer Science and Business Media LLC, 2019-09-01)
    The BCFW recursion relation in N = 4 super-Yang-Mills theory is solved using Yang-Baxter R-operators in the NMHV sector. Explicit expressions for R-invariants are obtained in terms of the chains of R-operators acting on an appropriate basic state.

    Periodic array of quantum rings strongly coupled to circularly polarized light as a topological insulator 
    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 ...

    Quantum ring with the Rashba spin-orbit interaction in the regime of strong light-matter coupling 
    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 ...

    Topological metamaterials based on polariton rings 
    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 ...

    Topology and symmetry-breaking in the strong light-matter coupling regime 
    Kozin, Valerii (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2021-08-30)
    The physics of light-matter interactions is a rapidly developing research area at the junction between condensed matter physics and quantum optics. Depending on the strength of the light-matter interaction the systems behave very differently. In the ...
