Theoretical modeling demonstrates robust mechanical squeezing in optomechanical resonators via interference-based Floquet control, highlighting a route to macroscopic quantum resources.
Key Points
To generate robust mechanical squeezing in optomechanical resonators by suppressing backscattering through destructive interference and applying periodic Floquet modulation.
Introduced an auxiliary nanoparticle to engineer a tunable scattering pathway that destructively interferes with defect-induced backscattering.
Applied a Floquet theoretical framework to model the periodic steady state and analyze phase-sensitive anomalous correlations under a modulated drive.
Destructive interference suppressed clockwise–counterclockwise mode mixing and restored a traveling-wave-dominated intracavity field.
Floquet modulation enhanced mechanical squeezing primarily through the buildup of phase-sensitive anomalous correlations rather than cooling alone.
Demonstrated robustness of the generated mechanical squeezing against thermal noise and finite angular misalignment.
