Vibrations of a Columnar Vortex in a Trapped Bose-Einstein Condensate
Lyndon Koens, Tapio P. Simula, Andrew M. Martin
We derive a governing equation for a Kelvin wave supported on a vortex line in a Bose-Einstein condensate, in a rotating cylindrically symmetric parabolic trap. From this solution…

Zero-energy states in rotating trapped Bose-Einstein condensates
Tapio Simula
We have calculated low-lying quasiparticle excitation spectra of rotating three-dimensional Bose-Einstein condensates. As opposed to the prediction of hydrodynamic continuum theori…

Synthetic charge-flux quantum liquids
Tapio P Simula
We apply rotating optical flux lattices to spinor Bose-Einstein condensates. Distinct quantum states emerge for fractional ratios of vortex charge density to optical flux density.…
