Boundary-driven delayed-feedback control of spatiotemporal dynamics in excitable media
Sebastian Echeverria-Alar, Wouter-Jan Rappel
Scroll-wave instabilities in excitable domains are central to life-threatening arrhythmias, yet practical methods to stabilize these dynamics remain limited. Here, we investigate t…
