Description
Discrete time crystals are a many-body state of matter where time translation symmetry is spontaneously broken in a periodically driven system. In view of the intense debate regarding the minimal requirements for the realization of a discrete time crystal, here we present a very pedagogical example of a many-body time crystal using coupled parametric resonators. We use classical bifurcation theory to study this resonator network and provide a clear distinction between an effective single mode and a truly many body time-translation symmetry breaking. We experimentally demonstrate this paradigm using two coupled mechanical oscillators, thus providing a clear route for time crystals realizations in real materials.
