We propose a superconducting circuit comprising a dc superconducting quantum interference device with a mechanically compliant arm embedded in a coplanar microwave cavity that realizes an optomechanical system with a degenerate or nondegenerate parametric interaction generated via the dynamical Casimir effect. For experimentally feasible parameters, this setup is capable of reaching the single-photon ultrastrong-coupling regime while simultaneously possessing a parametric coupling strength…

It is experimentally feasible to directly detect this nonclassical broadband radiation and the power of the radiation is estimated for realistic parameters and shown to be identical to the one calculated in the dynamical Casimir effect for a single oscillating mirror.
Multimode circuit optomechanics near the quantum limit

A hybrid optomechanical system having three degrees of freedom, consisting of a microwave cavity and two micromechanical beams with closely spaced frequencies around 32 MHz and no direct interaction is investigated, implying that the eigenmodes are combinations of one photonic and two phononic modes.
