Collective synchronization states in arrays of driven colloidal oscillators by Lhermerout, R, Bruot, N, Cicuta, G, Kotar, J, Cicuta, P

“…In this work, we coarse-grain the degrees of freedom of each cilium into a minimal description in terms of a configuration-based phase oscillator. Driving colloidal particles with optical tweezers, we then experimentally investigate the coupling through hydrodynamics in systems of many oscillators, showing that a collective dynamics emerges. …”
