Summary:
Chimera states are exotic solutions arising in complex dynamics, typically in networks of coupled oscillators. They are characterized by a cluster arrangement within the network, each cluster being identified by a particular behavior of all of its individual oscillators. Chimeras appear thus as the occurrence of stable neighboring groups (the clusters) of oscillators, each oscillator motion being uniform within one cluster, but incongruent between clusters. We report the experimental, numerical, and theoretical observation of such virtual Chimera states in a particular class of complex dynamical system modeled by a nonlinear delay integro-differential equation. The corresponding experimental setup involves an optoelectronic delay oscillator in which the dynamical variable is the wavelength of a tunable laser diode.
