Vortex waves in trapped Bose-Einstein condensates
arXiv:0809.0993 · doi:10.1103/PhysRevA.78.053604
Abstract
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 singly quantized vortex lines. Growth and decay dynamics of both types of vortex waves are discussed. We propose a method to experimentally create these vortex waves on demand.
