  Systems of nonlocally coupled oscillators can exhibit complex spatio-temporal
patterns, called chimera states, which consist of coexisting domains of
spatially coherent (synchronized) and incoherent dynamics. We report on a novel
form of these states, found in a widely used model of a limit-cycle oscillator
if one goes beyond the limit of weak coupling typical for phase oscillators.
Then patches of synchronized dynamics appear within the incoherent domain
giving rise to a multi-chimera state. We find that, depending on the coupling
strength and range, different multi-chimeras arise in a transition from
classical chimera states. The additional spatial modulation is due to strong
coupling interaction and thus cannot be observed in simple phase-oscillator
models.
