Dynamics of quantized vortices in superfluid helium and rotating Bose-Einstein condensates
Makoto Tsubota, Kenichi Kasamatsu, Tsunehiko Araki
In this article, we review the research on the dynamics of quantized vortices in superfluid helium and rotating Bose-Einstein condensates. First, after briefly reviewing the earlie…
Quadrupole-scissors modes and nonlinear mode coupling in trapped two-component Bose-Einstein condensates
Kenichi Kasamatsu, Makoto Tsubota, Masahito Ueda
We theoretically investigate quadrupolar collective excitations in two-component Bose-Einstein condensates and their nonlinear dynamics associated with harmonic generation and mode…
Vortex phase diagram in rotating two-component Bose-Einstein condensates
Kenichi Kasamatsu, Makoto Tsubota, Masahito Ueda
We investigate the structure of vortex states in rotating two-component Bose-Einstein condensates with equal intracomponent but varying intercomponent coupling constants. A phase d…
Nonlinear dynamics for vortex lattice formation in a rotating Bose-Einstein condensate
Kenichi Kasamatsu, Makoto Tsubota, Masahito Ueda
We study the response of a trapped Bose-Einstein condensate to a sudden turn-on of a rotating drive by solving the two-dimensional Gross-Pitaevskii equation. A weakly anisotropic r…
Vortex Nucleation and Array Formation in a Rotating Bose-Einstein Condensate
Makoto Tsubota, Kenichi Kasamatsu, Masahito Ueda
We study the dynamics of vortex lattice formation of a rotating trapped Bose-Einstein condensate by numerically solving the two-dimensional Gross-Pitaevskii equation, and find that…
