  We report on the emergence of robust multi-clustered chimera states in a
dissipative-driven system of symmetrically and locally coupled identical SQUID
oscillators. The "snake-like" resonance curve of the single SQUID
(Superconducting QUantum Interference Device) is the key to the formation of
the chimera states and is responsible for the extreme multistability exhibited
by the coupled system that leads to attractor crowding at the geometrical
resonance (inductive-capacitive) frequency. Until now, chimera states were
mostly believed to exist for nonlocal coupling. Our findings provide
theoretical evidence that nearest neighbor interactions are indeed capable of
supporting such states in a wide parameter range. SQUID metamaterials are the
subject of intense experimental investigations and we are highly confident that
the complex dynamics demonstrated in this manuscript can be confirmed in the
laboratory.
