Two-Dimensional Vortex Dynamics with Background Vorticity

Abstract

Magnetized electron plasmas have been used to study the dynamics of two-dimensional vortices in a cloud of background vorticity. Experiments have shown that background vorticity can calm chaotic vortex motion and cool a system of intense vortices into a crystal equilibrium. Further experiments have shown that weak vortices tend to migrate to extreme in the background vorticity distribution. The electron plasma experiments have motivated new theories on two-dimensional vortex dynamics with background vorticity. The experiments and related theories are summarized.
