2015/3/18
Researchers at the Universities of Strathclyde and Pittsburgh, and Princeton University, conducted a test in which they were able to arrange the particles into a ‘ring geometry’ form in a solid-state ...
Vortex-phonon interaction
Quantization vortex superfluids vortex dynamics launch elementary excitation inelastic scattering acoustic radiation fluid turbulence
2014/12/20
Kelvin waves—helical waves on quantized vortex lines—are the normal modes of vortices in a superfluid. At zero temperature, the only dissipative channel of vortex dynamics is phonon emission. Starting...
Vortex-phonon interaction in the Kosterlitz-Thouless theory

2014/12/20
The “canonical” variables of the Kosterlitz-Thouless theory—fields Φ0(r) and φ(r), generally believed to stand for vortices and phonons (or their XY equivalents, like spin waves, etc.) turn out to be ...
Effects of boundaries and density inhomogeneity on states of vortex matter in Bose-Einstein condensates at finite temperature
Quantum vortices 3 d eddy current condensate vortex entanglement
2014/12/19
Most of the literature on quantum vortices predicting various states of vortex matter in three dimensions at finite temperatures in quantum fluids is based on the assumption of an extended and homogen...
Unusual States of Vortex Matter in Mixtures of Bose-Einstein Condensates on Rotating Optical Lattices
Superfluid parameter space vortex lattice parameters the mixture of condensed matter optical lattice
2014/12/19
In a single-component superfluid under rotation a broken symmetry in the order parameter space results in a broken translational symmetry in real space: a vortex lattice. If translational symmetry is ...

2014/12/19
We study the evolution of rotational response of a statistical mechanical model of two-component superfluid with a nondissipative drag interaction as the system undergoes a transition into a paired su...

2014/12/18
Dynamics of quantized vortex lines in a superfluid feature symmetries associated with the geometric character of the complex-valued field, w(z)=x(z)+iy(z), describing the instant shape of the line. Al...
Alternate powers in Serrin's swirling vortex solutions

2012/4/23
We consider a modification of the fluid flow model for a swirling vortex developed by J. Serrin, where velocity decreases as the reciprocal of the distance from the vortex axis. Recent studies, based ...
Rotating superfluids in anharmonic traps: From vortex lattices to giant vortices

2011/10/9
Abstract: We study a superfluid in a rotating anharmonic trap and explicate a rigorous proof of a transition from a vortex lattice to a giant vortex state as the rotation is increased beyond a limitin...
Abstract: We analyze conformal blocks with multiple (semi-)degenerate field insertions in Liouville/Toda conformal field theories an show that their vector space is fully reproduced by the four-dimens...
The Abelian Higgs model is an appropriate field theoretic framework for the description of super-conductivity and its topological excitations(Nielson-Olesen-Abrikosov vortex). Recently, C.-Y. Hou etl ...
