Negative filament tension of scroll rings in an excitable system

Negative filament tension of scroll rings in an excitable system
Negative filament tension of scroll rings in an excitable system
Scroll rings are three-dimensional spiral waves of excitation that rotate around circular filaments. In a modified Belousov-Zhabotinsky reaction, these filaments expand, buckle, and build up gradients in rotation phase. The instability is caused by negative filament tension (−4.3×10−4cm2/s). Initial deformations are strongest in the direction normal to the filament’s osculating plane, and their growth rates decrease rapidly with increasing wave number.

Abstract

Scroll rings are three-dimensional spiral waves of excitation that rotate around circular filaments. In a modified Belousov-Zhabotinsky reaction, these filaments expand, buckle, and build up gradients in rotation phase. The instability is caused by negative filament tension (−4.3×10−4cm2/s). Initial deformations are strongest in the direction normal to the filament’s osculating plane, and their growth rates decrease rapidly with increasing wave number.
