    Duplication, Collapse, and Escape of Magnetic Skyrmions Revealed Using a Systematic Saddle Point Search Method 
    Müller, Gideon Philipp; Bessarab, Pavel; Vlasov, Sergei M.; Lux, Fabian; Kiselev, Nikolai S.; Blügel, Stefan; Uzdin, Valery M.; Jónsson, Hannes (American Physical Society (APS), 2018-11-06)
    Various transitions that a magnetic Skyrmion can undergo are found in calculations using a method for climbing up the energy surface and converging onto first order saddle points. In addition to collapse and escape through a boundary, the method ...

    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 ...

    Optimal Control of Magnetization Reversal in a Monodomain Particle by Means of Applied Magnetic Field 
    Kwiatkowski, Grzegorz J.; Badarneh, Mohammad H. A.; Berkov, Dmitry V.; Bessarab, Pavel (American Physical Society (APS), 2021-04-29)
    A complete analytical solution to the optimal reversal of a macrospin with easy-axis anisotropy is presented. An optimal control path minimizing the energy cost of the reversal is identified and used to derive the time-dependent direction and amplitude ...

    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 ...
