A correlation with phonons sustained by a FISH OIL pair of electromechanical resonators that differ both in size and frequency is demonstrated.In spite of the electromechanical resonators being spatially distinct, they can still be strongly dynamically coupled via a classical analogue of the beam splitter interaction with a cooperativity exceeding five, and parametric down-conversion which results in both resonators self-oscillating.This latter regime yields a classical variant of a two-mode squeezed state which is identified as perfectly correlated phase-locked vibrations between the two resonators.The creation of a correlation between two separate mechanical resonators suggests that extending this interaction to vacuum phonon states could enable a macroscopic two-mode squeezed state to be generated.

Conversely, the ability to resolve the correlated state via the self-oscillations Painter Jean could be harnessed to build a new class of detector where an external stimulus neutralises the phase-locked vibrations.
