Dissipative structures of quantized vortices in a coherently pumped polariton superfluid
Tomohiko Aioi, Tsuyoshi Kadokura, Hiroki Saito
Steady states reached in a coherently pumped exciton-polariton superfluid are investigated. As the pump parameter is changed, the translational symmetry of the uniform system is sp…
Modulation of a quantized vortex street with a vibrating obstacle
Hiroki Saito, Kenta Tazaki, Tomohiko Aioi
Dynamics of a superfluid flow past an obstacle are investigated by solving the Gross-Pitaevskii equation numerically. For an appropriate velocity and size of the obstacle, quantize…
Order-disorder oscillations in exciton-polariton superfluids
Hiroki Saito, Tomohiko Aioi, Tsuyoshi Kadokura
The dynamics of an exciton-polariton superfluid resonantly pumped in a semiconductor microcavity are investigated by mean-field theory. Modulational instability develops into cryst…
Bénard-von Kármán vortex street in an exciton-polariton superfluid
Hiroki Saito, Tomohiko Aioi, Tsuyoshi Kadokura
The dynamics of an exciton--polariton superfluid resonantly injected into a semiconductor microcavity are investigated numerically. The results reveal that a Bénard--von Kármán vor…
Penetration of a vortex dipole across an interface of Bose-Einstein condensates
Tomohiko Aioi, Tsuyoshi Kadokura, Hiroki Saito
The dynamics of a vortex dipole in a quasi-two dimensional two-component Bose-Einstein condensate are investigated. A vortex dipole is shown to penetrate the interface between the…
Symmetry breaking Rayleigh-Taylor instability in a two-component Bose-Einstein condensate
Tsuyoshi Kadokura, Tomohiko Aioi, Kazuki Sasaki +2
The interfacial instability and subsequent dynamics in a phase-separated two-component Bose-Einstein condensate with rotation symmetry are studied. When the interatomic interaction…
