No-flux boundaries stabilize scroll rings in excitable media with negative filament tension
Arash Azhand, Rico Buchholz, Florian Buchholz +2
Scroll rings in an unbounded excitable medium with negative line tension undergo an instability ending eventually in a "turbulent" state, known as scroll wave (Winfree) turbulence.…

Spatial Confinement Causes Lifetime Enhancement and Expansion of Vortex Rings with Positive Filament Tension
Jan F. Totz, Harald Engel, Oliver Steinbock
We study the impact of spatial confinement on the dynamics of three-dimensional excitation vortices with circular filaments. In a chemically active medium we observe a decreased co…
