Abstract

We have demonstrated that a classical metamaterial nanostructure, a two-dimensional array of plasmonic metamolecules supported on flexible nanowires, can be driven to a state possessing all the key features of a continuous time crystal - an eagerly-sought state of matter with properties periodic in time, rather than in space. The phenomenon points to the possibility of a new mechanism for the synchronization of noise-driven, linear oscillators based upon non-reciprocal coupling (non-Hamiltonian optical forces) between metamolecules.
