    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 ...

    Proton Shuttling and Reaction Paths in Dissociative Electron Attachment to o- and p-Tetrafluorohydroquinone, an Experimental and Theoretical Study 
    Ómarsson, Benedikt; Bjornsson, Ragnar; Ingólfsson, Oddur (American Chemical Society (ACS), 2017-07-21)
    Here we present a combined experimental and theoretical study on the fragmentation of o- and p-tetrafluorohydroquinone upon low energy electron attachment. Despite an identical ring-skeleton and identical functional groups in these constitutional ...

    Pulsed EPR dipolar spectroscopy at Q- and G-band on a trityl biradical 
    Akhmetzyanov, D.; Schöps, P.; Marko, A.; Kunjir, N. C.; Sigurdsson, Snorri; Prisner, Thomas F. (Royal Society of Chemistry (RSC), 2015)
    Pulsed electron paramagnetic resonance (EPR) spectroscopy is a valuable technique for the precise determination of distances between paramagnetic spin labels that are covalently attached to macromolecules. Nitroxides have commonly been utilised as ...

    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 ...

    A semi-rigid isoindoline-derived nitroxide spin label for RNA 
    Gophane, Dnyaneshwar B.; Endeward, Burkhard; Prisner, Thomas F.; Sigurdsson, Snorri (Royal Society of Chemistry (RSC), 2018)
    A new isoindoline-derived benzimidazole nitroxide spin label, ImUm, was synthesized and incorporated into RNA oligoribonucleotides. ImUm is the first example of a conformationally unambiguous spin label for RNA, in which the nitroxide N–O bond lies on ...

    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 ...
