  • Control of chimera states in oscillator networks
    Ruzzene, Giulia (Universitat Pompeu Fabra, 2020-09-25)
    Partial synchronization is an important phenomenon observed in nature and model systems. Chimera states are the most studied type of partially synchronized dynamics and attract interest from many fields of science. In ...
  • Controlling chimera states via minimal coupling modification
    Ruzzene, Giulia; Omelchenko, Iryna; Schöll, Eckehard; Zakharova, Anna; Andrzejak, Ralph Gregor (American Institute of Physics (AIP), 2019)
    We propose a method to control chimera states in a ring-shaped network of nonlocally coupled phase oscillators. This method acts exclusivelyon the network’s connectivity. Using the idea of a pacemaker oscillator, we ...
  • Generalized synchronization between chimera states
    Andrzejak, Ralph Gregor; Ruzzene, Giulia; Malvestio, Irene (American Institute of Physics (AIP), 2017)
    Networks of coupled oscillators in chimera states are characterized by an intriguing interplay of synchronous and asynchronous motion. While chimera states were initially discovered in mathematical model systems, there is ...
  • Generalized synchronization between chimera states [software]
    Andrzejak, Ralph Gregor; Ruzzene, Giulia; Malvestio, Irene (2017)
    This page provides the source code underlying the manuscript: Andrzejak RG, Ruzzene G, Malvestio I. 2017. Generalized synchronization between chimera states. Chaos. 27(5): 053114 If you use any of these resources, please ...
  • Mean field phase synchronization between chimera states
    Andrzejak, Ralph Gregor; Ruzzene, Giulia; Malvestio, Irene; Schindler, Kaspar A.; Schöll, Eckehard; Zakharova, Anna (American Institute of Physics (AIP), 2018)
    We study two-layer networks of identical phase oscillators. Each individual layer is a ring network for which a non-local intra-layer coupling leads to the formation of a chimera state. The number of oscillators and their ...
  • Remote pacemaker control of chimera states in multilayer networks of neurons
    Ruzzene, Giulia; Omelchenko, Iryna; Sawicki, Jakub; Zakharova, Anna; Schöll, Eckehard; Andrzejak, Ralph Gregor (American Physical Society, 2020)
    Networks of coupled nonlinear oscillators allow for the formation of nontrivial partially synchronized spatiotemporal patterns, such as chimera states, in which there are coexisting coherent (synchronized) and incoherent ...
  • Two populations of coupled quadratic maps exhibit a plentitude of symmetric and symmetry broken dynamics
    Andrzejak, Ralph Gregor; Ruzzene, Giulia; Schöll, Eckehard; Omelchenko, Iryna (American Institute of Physics (AIP), 2020)
    We numerically study a network of two identical populations of identical real-valued quadratic maps. Upon variation of the coupling strengths within and across populations, the network exhibits a rich variety of ...
