Metastability in the stochastic nearest-neighbor Kuramoto model of coupled phase oscillators
Nils Berglund, Georgi S. Medvedev, Gideon Simpson
The Kuramoto model (KM) of coupled phase-oscillators is analyzed in this work. The KM on a Cayley graph possesses a family of steady state solutions called twisted states. Topo…
