Some of the world’s most important discoveries – penicillin, vulcanized rubber and Velcro, to name a few – were made by accident. In fact, it’s been said that upward of half of all scientific discover...
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 ...
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     Variables  whirlpool  rotating wave  nonphysical  small vortex       font style='font-size:12px;'> 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 ...
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...
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 ...
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...
We use analytical arguments and large-scale Monte Carlo calculations to investigate the nature of the phase transitions between distinct complex superfluid phases in a two-component Bose-Einstein cond...
Geometric symmetries in superfluid vortex dynamics     Quantization  vortex line  fluid dynamics  fluid flow  vortex dynamics       font style='font-size:12px;'> 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...
Focusing properties of the double-vortex beams through a high numerical-aperture objective.
The convergence characteristics of two viscous core corrections as used in straight-line segmentation methods are rigorously analysed. These are \emph{curvature corrections} that account for the induc...
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 ...
Phase locking dynamics of dipolarly coupled vortices excited by spin-polarized current in two identical nanopillars is studied as a function of the interpillar distance L. Numerical study and analytic...
Based on the extended Huygens–Fresnel principle, we study the propagation properties of stochastic electro-magnetic double-vortex beams in turbulent atmosphere. The result shows that the spreading of ...
We investigate the torque on a specially shaped rotator produced by a vortex beam. The formulas for the torque alongx, yandzdirections are derived, and numerically calculation is performed. It is foun...
