Chimera states emerging from dynamical trapping in chaotic saddles
Everton S. Medeiros, Oleh Omel'chenko, Ulrike Feudel
Nonlinear systems possessing nonattracting chaotic sets, such as chaotic saddles, embedded in their state space may oscillate chaotically for a transient time before eventually tra…
Routes to extreme events in dynamical systems: Dynamical and Statistical Characteristics
Arindam Mishra, S. Leo Kingston, Chittaranjan Hens +3
Intermittent large amplitude events are seen in the temporal evolution of a state variable of many dynamical systems. Such intermittent large events suddenly start appearing in dyn…
Weak-winner phase synchronization: A curious case of weak interactions
Anshul Choudhary, Arindam Saha, Samuel Krueger +4
We report the observation of a novel and non-trivial synchronization state in a system consisting of three oscillators coupled in a linear chain. For certain ranges of coupling str…
The Boundaries of Synchronization in Oscillators Networks
Everton S Medeiros, Rene O. Medrano-T, Iberê L Caldas +1
We analyze the final state sensitivity of nonlocal networks with respect to initial conditions of their units. By changing the initial conditions of a single network unit, we pertu…
Complexity and irreducibility of dynamics on networks of networks
Leonardo Rydin Gorjão, Arindam Saha, Gerrit Ansmann +2
We study numerically the dynamics of a network of all-to-all-coupled, identical sub-networks consisting of diffusively coupled, non-identical FitzHugh--Nagumo oscillators. For a la…
Characteristics of in-out intermittency in delay-coupled FitzHugh-Nagumo oscillators
Arindam Saha, Ulrike Feudel
We analyze a pair of delay-coupled FitzHugh-Nagumo oscillators exhibiting in-out intermittency as a part of the generating mechanism of extreme events. We study in detail the chara…
