Vortex waves in trapped Bose-Einstein condensates
T. P. Simula, T. Mizushima, K. Machida
We have theoretically studied vortex waves of Bose-Einstein condensates in elongated harmonic traps. Our focus is on the axisymmetric varicose waves and helical Kelvin waves of sin…
Quasicondensation and coherence in the quasi-two-dimensional trapped Bose gas
R. N. Bisset, M. J. Davis, T. P. Simula +1
We simulate a trapped quasi-two-dimensional Bose gas using a classical field method. To interpret our results we identify the uniform Berezinskii-Kosterlitz-Thouless (BKT) temperat…
Kelvin Waves of Quantized Vortex Lines in Trapped Bose-Einstein Condensates
T. P. Simula, T. Mizushima, K. Machida
We have theoretically investigated Kelvin waves of quantized vortex lines in trapped Bose-Einstein condensates. Counterrotating perturbation induces an elliptical instability to th…
Superfluidity of an interacting trapped quasi-2D Bose gas
T. P. Simula, M. J. Davis, P. B. Blakie
We investigate the harmonically trapped interacting Bose gas in a quasi-2D geometry using the classical field method. The system exhibits quasi-long-range order and non-classical r…
Transition from Bose-Einstein Condensate to Berezinskii-Kosterlitz-Thouless Phase
T. P. Simula, M. D. Lee, D. A. W. Hutchinson
We obtain a phase diagram for a trapped two-dimensional ultra-cold Bose gas. We find a critical temperature above which the free energy of a state with a pair of vortices of opposi…
