Synchronizing Chaos with Imperfections

Previous research on nonlinear oscillator networks has shown that chaos synchronization is attainable for identical oscillators but deteriorates in the presence of parameter mismatches. Here, we identify regimes which opposite occurs and show heterogeneity can synchronize conditions under cannot. This effect not limited to small mismatches observed random both homogeneous heterogeneous network structures. The results are demonstrated experimentally using Chua's further supported by numerical simulations theoretical analysis. In particular, propose a general mechanism based heterogeneity-induced mode mixing provides insights into phenomenon. Since individual differences ubiquitous often unavoidable real systems, it follows such imperfections be an unexpected source stability.
