Título: | Mobility induces global synchronization of oscillators in periodic extended systems |
Autor: | Peruani, Fernando; Nicola, Ernesto M. CSIC; Morelli, Luis G. | Fecha de publicación: | sep-2010 | Editor: | Institute of Physics Publishing | Citación: | New Journal of Physics 12: (2010) | Resumen: | We study synchronization of locally coupled noisy phase oscillators which move diffusively in a one-dimensional ring. Together with the disordered and the globally synchronized states, the system also exhibits several wave-like states which display local order. We use a statistical description valid for a large number of oscillators to show that for any finite system there is a critical spatial diffusion above which all wave-like solutions become unstable. Through Langevin simulations, we show that the transition to global synchronization is mediated by the relative size of attractor basins associated to wave-like states. Spatial diffusion disrupts these states and paves the way for the system to attain global synchronization. | Descripción: | 15 pages, 6 figures | Versión del editor: | http://dx.doi.org/10.1088/1367-2630/12/9/093029 | URI: | http://hdl.handle.net/10261/25746 | DOI: | 10.1088/1367-2630/12/9/093029 | ISSN: | 1367-2630 | E-ISSN: | 1367-2630 |
