The collective dynamics of many systems in biology and physics are well characterized by strongly coupled limit cycle oscillators, ranging from certain neural circuits to coupled Josephson junctions. So far it was believed that symmetry in these system forces the collective dynamics to be regular, for instance periodic. A new study has now uncovered that equally chaos can emerge in such system, and in which forms it does.

The study is published in Physical Review Letters
