Vortex pseudomomentum and dissipation in a superfluid vortex lattice

Vortex Dissipation in Superfluid Third Sound Flows

Stability of the vortex lattice in a rotating superfluid.

We analyze the stability of the vortex lattice in a rotating superfluid against thermal fluctuations associated with the long-wavelength Tkachenko modes of the lattice. Inclusion of only the two-dimensional modes leads formally to instability in infinite lattices; however, when the full three-dimensional spectrum of modes is taken into account, the thermallyinduced lattice displacements are ind...

Vortex nucleation in superfluid

W F Vinen suggested in 1961 that the creation of quantized vortex line in superfluid 4He is impeded by an energy barrier. Measurements of the rate ν at which negative ions nucleate vortices in isotopically pure 4He have vindicated this idea. Barrier heights derived from the measured temperature dependence of ν are in good agreement with values calculated by Muirhead, Vinen and Donnelly (MVD) on...

Superfluid Vortex Nucleation

In an earlier paper 2] the author introduced a nonlinear Schrr odinger model for superruid that captures the process of mutual friction between the super-uid and normal uid components of helium II. Topological defects in the solution of this equation are identiied as superruid vortices, and in that paper, an asymp-totic dynamics for the vortices was derived in the case they are widely separated...

The Cantorian Superfluid Vortex Hypothesis

The present article suggests a preliminary version of Cantorian superfluid vortex hypothesis as a plausible model of nonlinear cosmology. Using the proposed model we explain the physical origin of quantum-like approach to describe planetary orbits as proposed in the recent literature. The meaning of the Cantorian superfluid vortex hypothesis is discussed, particularly in the context of offering...
