Synchronization of non-weakly coupled aeroelastic oscillators
Synchronized oscillators are ubiquitous in nature and engineering. Despite several models that have been proposed to treat synchronized oscillators beyond weak coupling, the widely accepted paradigm holds that synchronization occurs due to weak interactions between oscillating objects, hence limiting the predictive power of such models to the weak coupling limit. Here, we report a theoretical modeling and experimental observation of a synchronized pair of non-weakly coupled aeroelastic oscillators. We find quantitative agreement between the experiments and our theoretical higher-order phase model of non-weak coupling. Our results establish that synchronization experiments can be accurately reproduced and interpreted by theoretical modeling of non-weakly coupled oscillators, extending the range of validity and prediction power of theoretical phase models beyond the weak coupling limit. Synchronization between self-sustained oscillators is ubiquitous in nature and engineering, and it is generally accepted to occur due to weak interactions between the oscillating objects. The authors challenge this paradigm by presenting a theoretical higher-order phase model for non-weak coupling validated through experiments.
期刊介绍:
Communications Physics is an open access journal from Nature Research publishing high-quality research, reviews and commentary in all areas of the physical sciences. Research papers published by the journal represent significant advances bringing new insight to a specialized area of research in physics. We also aim to provide a community forum for issues of importance to all physicists, regardless of sub-discipline.
The scope of the journal covers all areas of experimental, applied, fundamental, and interdisciplinary physical sciences. Primary research published in Communications Physics includes novel experimental results, new techniques or computational methods that may influence the work of others in the sub-discipline. We also consider submissions from adjacent research fields where the central advance of the study is of interest to physicists, for example material sciences, physical chemistry and technologies.
