Neutral Vortex Necklace in a Trapped Planar Superfluid
نویسندگان
چکیده
We study quantum vortex states consisting of a ring vortices with alternating sign, in homogeneous superfluid confined to circular domain. find an exact stationary solution the point model for neutral necklace. investigate stability necklace state within both point-vortex and Gross-Pitaevskii equation describing trapped atomic Bose-Einstein condensate at low temperature. The are found also be provided finite thickness outer fluid boundary is accounted for. Under significant perturbation, evolution exhibit instability as expected metastable states. perturbed exhibits sensitivity suggesting route seeding chaos or turbulence.

Large eddy simulation of propane combustion in a planar trapped vortex combustor
Propane combustion in a trapped vortex combustor (TVC) is characterized via large eddy simulation coupled with filtered mass density function. A computational algorithm based on high order finite difference (FD) schemes, is employed to solve the Eulerian filtered compressible Navier-Stokes equations. In contrast, a Lagrangian Monte-Carlo solver based on the filtered mass density function is inv...
متن کاملVortex 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...

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...
متن کاملVortices in trapped superfluid fermi gases.
We consider a superfluid of trapped fermionic atoms and study the single vortex solution in the Ginzburg-Landau regime. We define simple analytical estimates for the main characteristics of the system, such as the vortex core size, temperature regimes for the existence of a vortex, and the effects of rotation and interactions with normal fermions. The parameter dependence of the vortex core siz...
متن کاملQuantum dynamics of a Bose superfluid vortex.
We derive a fully quantum-mechanical equation of motion for a vortex in a 2-dimensional Bose superfluid in the temperature regime where the normal fluid density ρ(n)(T) is small. The coupling between the vortex "zero mode" and the quasiparticles has no term linear in the quasiparticle variables--the lowest-order coupling is quadratic. We find that as a function of the dimensionless frequency Ω=...
