New type of chimera structures in a ring of bistable FitzHugh-Nagumo oscillators with nonlocal interaction

We study the spatiotemporal dynamics of a ring of nonlocally coupled FitzHugh-Nagumo oscillators in the bistable regime. A new type of chimera patterns has been found in the noise-free network and when isolated elements do not oscillate. The region of existence of these structures has been explored when the coupling range and the coupling strength between the network elements are varied. (C) 2017 Elsevier B.V. All rights reserved.
