Abstract:
We present conclusive evidence showing that different sources of diversity, such as those represented by quenched disorder or noise, can induce a resonant collective behavior in an ensemble of coupled bistable or excitable systems.
Our analytical and numerical results show that when such systems are
subjected to an external subthreshold signal, their response is
optimized for an intermediate value of the diversity. These findings
show that intrinsic diversity might have a constructive role and suggest that
natural systems might profit from their diversity in order to
optimize the response to an external stimulus.
