Chirality dependent component of vortex advection in excitable media

Voignier, V; Hamm, E; Krinsky, V

Abstract

An advective field induces drift of a vortex in excitable media. The component of the drift velocity C-perpendicular to perpendicular to the field is known to change its sign with the chirality of the vortex. In an experiment with vortices in an electric field in a chemical excitable medium, we have found unexpectedly that C-perpendicular to changes its sign also independently of chirality with changing composition of the medium. We did not succeed to explain this phenomenon by using existing mathematical models of chemical excitable media. The experiment described calls for more realistic models.
