  abstract     = {Strong optomechanical coupling -- a regime where mechanical motion is damped
by environmental radiation -- has traditionally required demanding experimental
ingredients such as superconducting resonators, high-quality optical cavities,
or large magnetic fields. Here we demonstrate a room temperature, cavity-free,
all-electric device reaching this regime at radio frequencies, enabled by a
mechanically compliant parallel-plate capacitor with a nanoscale plate
separation and an aspect ratio exceeding 1,000. The device has four orders of
magnitude lower insertion loss than a comparable commercial quartz crystal, and
achieves a position imprecision rivaling an optical interferometer. With the
help of a back-action isolation scheme, we observe radiative cooling of
mechanical motion by a remote cryogenic load. This work provides a
technologically accessible route to high-precision sensing, transduction, and
signal processing.},
