The coherence properties of mechanical resonators are often limited by multiple unavoidable forms of loss -- including phonon-phonon and phonon-defect scattering -- which result in the scattering of sound into other resonant modes and into the phonon bath. Dynamic suppression of this scattering loss can lift constraints on device structure and can improve tolerance to defects in the material, even after fabrication. Inspired by recent experiments, here we introduce a model of phonon losses…

Dynamically induced robust phonon transport and chiral cooling in an optomechanical system

Chiral phonon transport, disorder suppression and anomalous cooling without damping in an asymmetrically-pumped optomechanical system is demonstrated, resulting in improved resonant modes for sensing and metrology.

Optomechanically-induced chiral transport of phonons in one dimension

Non-reciprocal devices, with one-way transport properties, form a key component for isolating and controlling light in photonic systems. Optomechanical systems have emerged as a potential platform
