Evidence of Noise Induced Synchronization and Coherence Resonance in Homoclinic Chaos

摘要

We present experimental and numerical investigation of noise-induced synchronization (NIS) and coherence resonance (CR) in a system displaying homoclinic chaos. These two effects have been observed in one experimental laser system by using weak noise intensities that do not change the main geometrical features of the unperturbed dynamics. These nontrivial effects originating from the intrinsically strong nonuniform dynamics of homoclinic chaos are of grat relevance to neuroscience.
