Moving spiral wave chimeras
NettetSpiral waves are travelling waves that rotate outward from a center in a spiral. They are a feature of many excitable media . Spiral waves have been observed in various … Nettetscroll wave chimeras and the impact of inertia on scroll wave chimeras in a system without inertia are analyzed. We demonstrate that the 3D scroll wave chimeras can be surrounded by solitary oscillators [25, 26] (like a \soli-tary cloud") (Fig. 1 (c)). In [27], the spiral wave chimeras with solitary clouds have been studied in the case of the

Nettet28. aug. 2024 · It was established that nonlocal coupling can give rise to chimeras on the basis of spiral waves: so-called “spiral-wave chimeras” [ 4 – 7 ]. Clusters of incoherency of spiral-wave chimeras are circular cores surrounding an … Nettet1. mar. 2024 · Spiral wave patterns and spiral wave chimeras can also be found for periodic boundary conditions when the coupling range P increases. The number of incoherent cores also increases as P goes up. We analyze this dependence for the case of periodic boundary conditions and the resulting spatio-temporal patters are depicted in …
NettetHere, by coupling large populations of Stuart−Landau oscillators to a diffusive environment, we demonstrate that spiral wave chimeras do exist in this oscillator-environment coupling system even when τ is very large. Various transitions such as from spiral wave chimeras to spiral waves or unstable spiral wave chimeras as functions of the ... Nettet19. jan. 2024 · For spiral wave chimeras the initial condition is given by a phase distribution with a phase singularity ( 4.40 ), whereas the d -clusters with d=1,2 are …
Nettet8. mai 2024 · Another unusual characteristic of spiral wave chimeras is their erratic motion arising from the asynchronous oscillators in the core. While the dynamics of BZ … NettetIn the present article, we demonstrate the emergence and existence of the spiral wave chimera-like transient pattern in coupled ecological systems, composed of prey-predator patches, where the patches are connected in a three …
NettetFor fractal coupling schemes spiral wave chimeras are produced and curious stable patterns are reported, which present triple coexistence of coherent regions, incoherent domains and traveling waves.
