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…
Riddled Basins of Attraction in Systems Exhibiting Extreme Events
Arindam Saha, Ulrike Feudel
Using a system of two FitzHugh-Nagumo units, we demonstrate the occurrence of riddled basins of attraction in delay-coupled systems as the coupling between the units is increased.…
Recovery time after localized perturbations in complex dynamical networks
Chiranjit Mitra, Tim Kittel, Anshul Choudhary +2
Maintaining the synchronous motion of dynamical systems interacting on complex networks is often critical to their functionality. However, real-world networked dynamical systems op…
Extreme events in Fitzhugh-Nagumo oscillators coupled with two time delays
Arindam Saha, Ulrike Feudel
We study two identical FitzHugh-Nagumo oscillators which are coupled with one or two different time delays. If only a single delay coupling is used, the length of the delay determi…
Extreme events in excitable systems and mechanisms of their generation
Gerrit Ansmann, Rajat Karnatak, Klaus Lehnertz +1
We study deterministic systems, composed of excitable units of FitzHugh-Nagumo type, that are capable of self-generating and self-terminating strong deviations from their regular d…
Generalized synchronization in relay systems with instantaneous coupling
Ricardo Gutierrez, Ricardo Sevilla-Escoboza, Pablo Piedrahita +7
We demonstrate the existence of generalized synchronization in systems that act as mediators between two dynamical units that, in turn, show complete synchronization with each othe…
Different types of critical behavior in conservatively coupled Hénon maps
D. V. Savin, A. P. Kuznetsov, A. V. Savin +1
We study the dynamics of two conservatively coupled Hénon maps at different levels of dissipation. It is shown that the decrease of dissipation leads to changes in the parameter pl…
Plankton blooms in vortices: The role of biological and hydrodynamic time scales
M. Sandulescu, C. Lopez, E. Hernandez-Garcia +1
We study the interplay of hydrodynamic mesoscale structures and the growth of plankton in the wake of an island, and its interaction with a coastal upwelling. Our focus is on a mec…
Enhancement of Noise-induced Escape through the Existence of a Chaotic Saddle
Suso Kraut, Ulrike Feudel
We study the noise-induced escape process in a prototype dissipative nonequilibrium system, the Ikeda map. In the presence of a chaotic saddle embedded in the basin of attraction o…
Multistability and nonsmooth bifurcations in the quasiperiodically forced circle map
Hinke Osinga, Jan Wiersig, Paul Glendinning +1
It is well-known that the dynamics of the Arnold circle map is phase-locked in regions of the parameter space called Arnold tongues. If the map is invertible, the only possible dyn…
