The correlation coefficient for vortices in the plane [PDF]
For point vortices in the plane, we consider the correlation coefficient of Ovchinnikov and Sigal.

A liquid crystal Spatial Light Modulator (SLM) can be used in various ways to produce vector-vortices. Superposition of scalar vortices with orthogonal polarization is a common approach, while a more recent technique is to use dual-phase modulation ...

The merger of two-dimensional radially stratified high-Froude-number vortices [PDF]
We investigate the influence of density inhomogeneities on the merger of two corotating two-dimensional vortices at infinite Froude number. In this situation, buoyancy effects are negligible, yet density variations still affect the flow by pure inertial ...

Relaxation Dynamics of Point Vortices
We study a model describing relaxation dynamics of point vortices, from quasi-stationary state to the stationary state. It takes the form of a mean field equation of Brownian point vortices derived from Chavanis, and is formulated by our previous work as a limit equation of the patch model studied by Robert-Someria.

The shape of vortices in quasi-geostrophic turbulence [PDF]
Partially supported by the UK EPSRC (Grant GR/N11711)The present work discusses the most commonly occurring shape of the coherent vortical structures in rapidly rotating stably stratified turbulence, under the quasi-geostrophic approximation. In decaying

Evolutions of optical vortices under wide Gaussian background
Analytically discussed is the evolution properties of optical vortices superimposed by Gaussian backgrounds. A kind of Tornado-like pattern is obtained after linear propagations, when the Gaussian background is wide enough compared with optical vortices.

Point vortices on the hyperbolic plane [PDF]
We investigate the dynamical system of point vortices on the hyperboloid. This system has non-compact symmetry SL(2, R) and a coadjoint equivariant momentum map. The relative equilibrium conditions are found and the trajectories of relative equilibria with non-zero momentum value are described.

The merger of vertically offset quasi-geostrophic vortices [PDF]
We examine the critical merging distance between two equal-volume, equal-potential-vorticity quasi-geostrophic vortices. We focus on how this distance depends on the vertical offset between the two vortices, each having a unit mean height-to-width aspect

The critical merger distance between two co-rotating quasi-geostrophic vortices [PDF]
This paper examines the critical merger or strong interaction distance between two equal-potential-vorticity quasi-geostrophic vortices. The interaction between the two vortices depends on five parameters: their volume ratio, their height-to-width aspect
