Symmetry of vortex structures, axial currents, and Kelvin waves in super-fluid 3He
Sonin E. B., Fomin N. V.
A symmetry classification is offered for vortex structures in 3He. Kelvin waves are analyzedfor structures which allow axial currents. If the vessel is rotating at a low velocity Ω, and the wavelength is given, the oscillation frequency is a square-root function of fi, while the functional dependence is linear for structures without axial currents (in particular, in 4He).
