    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 ...

    Highly nonlinear trion-polaritons in a monolayer semiconductor 
    Emmanuele, R. P. A.; Sich, M.; Kyriienko, O.; Shahnazaryan, V.; Withers, F.; Catanzaro, A.; Walker, P. M.; Benimetskiy, F. A.; Skolnick, M. S.; Tartakovskii, A. I.; Shelykh, Ivan; Krizhanovskiǐ, Dmitry N. (Springer Science and Business Media LLC, 2020-07-17)
    Highly nonlinear optical materials with strong effective photon-photon interactions are required for ultrafast and quantum optical signal processing circuitry. Here we report strong Kerr-like nonlinearities by employing efficient optical transitions ...

    Transition from Propagating Polariton Solitons to a Standing Wave Condensate Induced by Interactions 
    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 ...
