摘要: We investigate numerically the dynamic properties of a system globally coupled oscillators driven by periodic symmetry-breaking fields in presence noise. The phase distribution is computed and transition disclosed. It further found that stochastic resonance closely related to behavior order parameter, which turn explained formation bi-cluster system. Here noise tends symmetrize motion oscillators, facilitating formation. observed appears be same class as present two-dimensional Ising model under oscillating fields.
