Excitable solitons: Annihilation, crossover, and nucleation of pulses in mass-conserving activator-inhibitor media
Excitable solitons: Annihilation, crossover, and nucleation of pulses in mass-conserving activator-inhibitor media
Excitable pulses are among the most widespread dynamical patterns that occur in many different systems, ranging from biological cells to chemical reactions and ecological populations. Traditionally, the mutual annihilation of two colliding pulses is regarded as their prototypical signature. Here we show that colliding excitable pulses may exhibit soliton-like crossover …
