Scroll Waves Pinned to Moving Heterogeneities
Hua Ke, Zhihui Zhang, Oliver Steinbock
Three-dimensional excitable systems can selforganize vortex patterns that rotate around one-dimensional phase singularities called filaments. In experiments with the Belousov-Zhabo…
Analysis of Anchor-Size Effects on Pinned Scroll Waves and Measurement of Filament Rigidity
Elias Nakouzi, Zulma A. Jiménez, Vadim N. Biktashev +1
Inert, spherical heterogeneities can pin three-dimensional scroll waves in the excitable Belousov-Zhabotinsky reaction. Three pinning sites cause initially circular rotation backbo…
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…
