Unstable dynamics, nonequilibrium phases, and criticality in networked excitable media
Unstable dynamics, nonequilibrium phases, and criticality in networked excitable media
Here we numerically study a model of excitable media, namely, a network with occasionally quiet nodes and connection weights that vary with activity on a short-time scale. Even in the absence of stimuli, this exhibits unstable dynamics, nonequilibrium phases -including one in which the global activity wanders irregularly among attractors- …
