  Chimera states have attracted significant attention as symmetry-broken states
exhibiting the unexpected coexistence of coherence and incoherence. Despite the
valuable insights gained from analyzing specific systems, an understanding of
the general physical mechanism underlying the emergence of chimeras is still
lacking. Here, we show that many stable chimeras arise because coherence in
part of the system is sustained by incoherence in the rest of the system. This
mechanism may be regarded as a deterministic analog of noise-induced
synchronization and is shown to underlie the emergence of strong chimeras.
These are chimera states whose coherent domain is formed by identically
synchronized oscillators. Recognizing this mechanism offers a new meaning to
the interpretation that chimeras are a natural link between coherence and
incoherence.
