Journal ArticleDOI
Vortex lattice formation in a rotating Bose-Einstein condensate
TL;DR: In this paper, the authors studied the dynamics of vortex lattice formation of a rotating trapped Bose-Einstein condensate by numerically solving the two-dimensional Gross-Pitaevskii equation.
Journal ArticleDOI
Kolmogorov spectrum of superfluid turbulence: numerical analysis of the Gross-Pitaevskii equation with a small-scale dissipation.
TL;DR: The dissipation term is introduced which works only in the scale smaller than the healing length to remove short wavelength excitations which may hinder the cascade process of quantized vortices in the inertial range.
Journal ArticleDOI
Vortices in multicomponent bose–einstein condensates
TL;DR: In this paper, the authors review the fundamental structure, stability and dynamics of a single vortex state in a slowly rotating two-component condensates and discuss a rich variety of vortex states realized in rapidly rotating 2-component Bose-Einstein Condensates.
Journal ArticleDOI

TL;DR: Nuclear magnetic resonance measurements and numerical simulations indicate the existence of sharp transition to turbulence in the B phase of superfluid 3He, which is insensitive to the fluid velocity, in striking contrast to current textbook knowledge of turbulence.
Journal ArticleDOI
Vortices in multicomponent Bose-Einstein condensates
TL;DR: In this paper, the authors review the fundamental structure, stability and dynamics of a single vortex state in a slowly rotating two-component condensates and present a phase diagram with axes of rotation frequency and the intercomponent coupling strength.
