Summary:Chimera states are spatiotemporal patterns of coexisting coherent and incoherent domains [1] that have attracted much attention within the community of nonlinear science over the past two decades [2]. In passive Kerr resonators, a localized domain of spatiotemporal chaos can be excited on a surrounding continous-wave (cw) background. However, instead of harmonious coexistence with the cw state, the chaotic domain tends to invade and completely overtake the coherent background [3,4]. By introducing temporal heterogeneity into the system, it should be possible to pin the (incoherent) chaotic domain [5,6], so that it coexists with the (coherent) cw state, hence creating a chimera-like state. This has yet to be demonstrated.
