Asymptotic motion of a single vortex in a rotating semiinfinite cylinder

J.M. Karimäki, R. Hänninen, E.V. Thuneberg

We study numerically the behavior of a single quantized vortex in a rotating cylinder. We study in particular the spiraling motion of a vortex in a cylinder that is parallel to the rotation axis. We determine the asymptotic form of the vortex and its axial and azimuthal propagation velocities under a wide range of parameters. We also study the stability of the vortex line and the effect of tilting the cylinder from the rotation axis.
