Quantum ferrofluid turbulence
T. Bland, G. W. Stagg, L. Galantucci +2
We study the elementary characteristics of turbulence in a quantum ferrofluid through the context of a dipolar Bose gas condensing from a highly non-equilibrium thermal state. Our…
Vortex scattering by impurities in a Bose-Einstein condensate
A. Griffin, G. W. Stagg, N. P. Proukakis +1
Understanding quantum dynamics in a two-dimensional Bose-Einstein condensate (BEC) relies on understanding how vortices interact with each others microscopically and with local imp…
Ultra-quantum turbulence in a quenched homogeneous Bose gas
G. W. Stagg, N. G. Parker, C. F. Barenghi
Using the classical field method, we study numerically the characteristics and decay of the turbulent tangle of superfluid vortices which is created in the evolution of a Bose gas…
Critical velocity of a finite-temperature Bose gas
G. W. Stagg, R. W. Pattinson, C. F. Barenghi +1
We use classical field simulations of the homogeneous Bose gas to study the breakdown of superflow due to vortex nucleation past a cylindrical obstacle at finite temperature. Therm…
Classical-like wakes past elliptical obstacles in atomic Bose-Einstein condensates
G. W. Stagg, A. J. Allen, C. F. Barenghi +1
We reinvestigate numerically the classic problem of two-dimensional superfluid flow past an obstacle. Taking the obstacle to be elongated (perpendicular to the flow), rather than t…
Generation and Decay of Two-Dimensional Quantum Turbulence in a Trapped Bose-Einstein Condensate
G. W. Stagg, A. J. Allen, N. G. Parker +1
In a recent experiment, Kwon et. al (arXiv:1403.4658 [cond-mat.quant-gas]) generated a disordered state of quantum vortices by translating an oblate Bose-Einstein condensate past a…
Quantum Analogs of Classical Wakes in Bose-Einstein Condensates
G. W. Stagg, N. G. Parker, C. F. Barenghi
We show that an elliptical obstacle moving through a Bose-Einstein condensate generates wakes of quantum vortices which resemble those of classical viscous flow past a cylinder or…
