Exotic states in a simple network of nanoelectromechanical oscillators
Abstract
Synchronizing oscillators have been useful models for exploring coupling in dynamic systems. However, many macroscopic platforms such as pendula evolve on slow time scales, which can limit the observation of states that emerge after many cycles. Matheny et al. fabricated a ring of eight nanoelectromechanical oscillators resonating at ∼2.2 megahertz with quality factors of ∼4000 that could be rapidly controlled and read out. Analysis of these large datasets revealed exotic synchronization states with complex dynamics and broken symmetries. Theoretical modeling showed that emergent higher-order interactions (such as biharmonic and next-nearest neighbor) stabilized complex dynamics, despite the network having weak nearest-neighbor coupling.
