Experimental Dynamics of a Vortex within a Vortex
Physical Review Letters, 2000We report the experimental dynamics of a new two-dimensional (2D) fluid phenomenon that occurs when an intense, pointlike vortex is placed within a diffuse, circular vortex. Our observations, made using strongly magnetized electron columns to model the 2D fluid, support the analysis performed by Jin and Dubin.

Physical Review E, 1996
Interaction of a point vortex sink (twister) with an obstacle in a stationary and nonstationary flow is considered. Classification of twister trajectories, depending on nondimensional parameters of the system, and the probability of twister-obstacle collisions are presented.

1993
The discovery of coherent structures in turbulence has fostered the hope that the study of vortices will lead to models and an understanding of turbulent flow, thereby solving or at least making less mysterious one of the great unsolved problems of classical physics.

Vortex dynamics and melting in niobium
Physical Review Letters, 1994Small angle neutron scattering has been used to investigate the vortex scattering in single crystal niobium. In the mixed state (${\mathit{H}}_{\mathit{c}1}$H${\mathit{H}}_{\mathit{c}2}$) a sixfold hexagonal pattern of peaks is observed at all temperatures.

Quantum dynamics of a single vortex
Nature, 2003Vortices occur naturally in a wide range of gases and fluids, from macroscopic to microscopic scales. In Bose-Einstein condensates of dilute atomic gases, superfluid helium and superconductors, the existence of vortices is a consequence of the quantum nature of the system.

Dynamic Melting of the Vortex Lattice
Physical Review Letters, 1994We investigate analytically and numerically the melting of the vortex lattice moving in an inhomogeneous environment under the applied current [ital j]. We predict the existence of a dynamic phase transition at some characteristic current [ital j]=[ital j][sub [ital t]] (crystallization current) from the motion of the amorphous vortex configuration at [

Dynamics of a Viscous Vortex Ring
International Journal of Fluid Mechanics Research, 1999The evolution of a viscous vortex ring through the use of the earlier obtained solution of the Stokes equations in the form of time-dependent vorticity distribution is studied. In the long-time limit this distribution transforms into the classical self-similar Phillips’ distribution and for t → 0 it reduces to a delta-function.

Dynamics of uniform vortex patch with a point vortex
IEEE Transactions on Plasma Science, 2002Vortex dynamics in two-dimensional inviscid, incompressible fluids are isomorphic to the dynamics of strongly magnetized guiding center plasmas restricted to E /spl times/ B motion. In this paper, we exploit this analogy and study the dynamics of a uniform vortex patch with a point-like vortex using a particle-in-cell code.

Viscous Vortex Dynamics on Surfaces
ACM Transactions on GraphicsWe present a vorticity method for simulating incompressible viscous flows on curved surfaces governed by the Navier-Stokes equations. Unlike previous approaches, our formulation incorporates the often-overlooked Gaussian-curvature-dependent term in the viscous force, which influences both the vorticity equation and the evolution of harmonic components.
