Coherent beating between oscillators is one of the most fundamental phenomena in physics, with the simplest example being a pair of coupled pendula. When two pendula are coupled, they coherently transfer energy between them. However, in real systems this behavior is transient and disappears in steady-state due to dissipation and non-linear interactions. The paper shows theoretically and experimentally that coupled parametric oscillators can exhibit persistent coherent beats even in steady-state. This behavior can have implications for networks of parametric oscillators and coherent systems in general.
