Plasmas consisting exclusively of particles with a single sign of charge (eg, pure electron
plasmas and pure ion plasmas) can be confined by static electric and magnetic fields (in a …

Two-dimensional turbulence normally relaxes through vortex merger and filamentation, with
energy flowing to large scales and enstrophy dissipated on fine scales. Experiments on …

The inviscid evolution of elliptical, nonuniform vorticity distributions is studied
computationally using a high resolution Lagrangian (vortex) method with minimal numerical …

The inviscid damping of an asymmetric perturbation on a two-dimensional circular vortex is
examined theoretically, and with an electron plasma experiment. In the experiment, an …

During the last fifty years, nonneutral plasma physics has developed into a definite subfield
of basic research, whose main focus has been on the collective properties of systems …

This paper further examines the rate at which potential vorticity in the core of a monotonic
cyclone becomes vertically aligned and horizontally axisymmetric. We consider the case in …

Slightly non-axisymmetric vortices are analysed by asymptotic methods in the context of
incompressible large-Reynolds-number two-dimensional flows. The structure of the non …

Pure electron plasma columns are contained inside hollow conducting cylinders in an axial
magnetic field. In the 2D E× B drift approximation, an electron column is a vortex evolving in …

Based on experimental evidence, explicit vorticity-distributed solutions to the Euler
equations in two dimensions are constructed describing the tripole vortex. The vortex form …

Thanks to the isomorphism between the drift-Poisson and Euler equations, inviscid two-
dimensional fluid experiments can be performed in magnetized, single-component plasmas …
