Coloquio de Física - Synchronization in populations of chemical oscillators: quorum sensing, phase clusters, and chimeras

   Departamentos        Ciencias - Sección Física

Ponente: Kenneth Showalter (West Virginia University) We have studied large, heterogeneous populations of discrete chemical oscillators (~100 000) to characterize two different types of density-dependent transitions to synchronized behavior: a gradual Kuramoto synchronization and a sudden quorum sensing synchronization. We also describe the formation of phase clusters, where each cluster has the same frequency but is phase-shifted with respect to other clusters, giving rise to a global signal that is more complex than that of the individual oscillators. Finally, we describe experimental and modeling studies of chimera states and their relation to other synchronization states in populations of coupled chemical oscillators
