Microscopic Variability Alters Macroscopic Rotation Speed in Stochastic Spiral Waves
Jolien Kamphuis, Desmond Kabus, Hermen Jan Hupkes +1
We present a general theory for noise-induced corrections to the angular velocity of spiral waves. Stochasticity produces two second-order effects: an instantaneous term from heter…

Strings, branes and twistons: topological analysis of phase defects in excitable media such as the heart
Louise Arno, Desmond Kabus, Hans Dierckx
Several excitable systems, such as the heart, self-organize into complex spatio-temporal patterns that involve wave collisions, wave breaks, and rotating vortices, of which the dyn…
