The correlation coefficient for vortices in the plane [PDF]

, 2019
For point vortices in the plane, we consider the correlation coefficient of Ovchinnikov and Sigal.

Generation of V-point polarization singularity using single phase encoding with a spatial light modulator

Scientific Reports, 2023
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 ...

Dynamics of several point vortices for the lake equations [PDF]

, 2023
International audienceThe global asymptotic dynamics of point vortices for the lake equations is rigorously derived. Vorticity that is initially sharply concentrated around $N$ distinct vortex centers is proven to remain concentrated for all times ...

Relaxation Dynamics of Point Vortices

, 2022
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.

Interactions of point vortices in the Zabusky-McWilliams model with a background flow [PDF]

, 2012
We combine a simple quasi-geostrophic flow model with the Zabusky-McWilliams theory of atmospheric vortex dynamics to address a hurricane-tracking problem of interest to the insurance industry.

Evolutions of optical vortices under wide Gaussian background

Results in Physics, 2021
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.

Spatial distribution of rolled up Kelvin-Helmholtz vortices at Earth's dayside and flank magnetopause [PDF]

, 2012
The Kelvin-Helmholtz Instability (KHI) can drive waves at the magnetopause. These waves can grow to form rolled-up vortices and facilitate transfer of plasma into the magnetosphere.

Statistics and dynamics of blockings with a point vortex model

Tellus: Series A, Dynamic Meteorology and Oceanography, 2018
We investigate a reduced point vortex model for statistical and dynamical analyses of atmospheric blocking phenomena. Thereby, we consider High-over-low and Omega blocking as relative equilibria of two and three point vortices.

Vortex Structure and Kinematics of Encased Axial Turbomachines

International Journal of Turbomachinery, Propulsion and Power, 2018
This paper models the kinematics of the vortex system of an encased axial turbomachine at part load and overload applying analytical methods. Thus far, the influence of the casing and the tip clearance on the kinematics have been solved separately.
