Abstract

Synchronization of oscillators, a phenomenon found in a wide variety of natural and engineered systems, is typically understood through a reduction to a first-order phase model with simplified dynamics. Here, by exploiting the precision and flexibility of nanoelectromechanical systems, we examined the dynamics of a ring of quasi-sinusoidal oscillators at and beyond first order. Beyond first order, we found exotic states of synchronization with highly complex dynamics, including weak chimeras, decoupled states, traveling waves, and inhomogeneous synchronized states. Through theory and experiment, we show that these exotic states rely on complex interactions emerging out of networks with simple linear nearest-neighbor coupling. This work provides insight into the dynamical richness of complex systems with weak nonlinearities and local interactions.

All authors discussed the results and their implications equally at all stages. Competing interests: None declared. Data and materials availability: All (other) data needed to evaluate the conclusions in the paper are available in the following online database: 10.5281/zenodo.2543765. All experiments, numerical simulations, and data processing were performed with custom Python and C scripts. Signals were acquired through use of a simultaneous-sampling 8-channel oscilloscope. Oscillator phase was extracted via a Hilbert transform of raw time records from the oscilloscope. Oscilloscope sampling was set to 200 kHz, which is faster than the slow-time oscillator dynamics by about three orders of magnitude.
