    All-optical band engineering of gapped Dirac materials 
    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 ...

    Effect of BN dimers on the stability, electronic, and thermal properties of monolayer graphene 
    Abdullah, Nzar Rauf; Abdalla, Danyal A.; Ahmed, Taha Y.; Abdulqadr, Sarbast W.; Rashid, Hunar Omar (Elsevier BV, 2020-09)
    We theoretically investigate structural stability, electronic and thermal characteristic of boron and nitrogen codoped monolayer graphene using density functional theory and Boltzmann transport equation. Three types of BN dimers, ortho, meta, and para ...

    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 ...

    Optically induced Lifshitz transition in bilayer graphene 
    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 ...

    Silicon on a graphene nanosheet with triangle- and dot-shape: Electronic structure, specific heat, and thermal conductivity from first-principle calculations 
    Rashid, Hunar Omar; Abdullah, Nzar; Gudmundsson, Vidar (Elsevier BV, 2019-12)
    The electronic structure, specific heat, and thermal conductivity of silicon embedded in a monolayer graphene nanosheet are studied using Density Functional Theory. Two different shapes of the substitutional Si doping in the graphene are studied, a ...
