  abstract     = {The back-action damping of mechanical motion by electromagnetic radiation is typically overwhelmed by internal loss channels unless demanding experimental ingredients such as superconducting resonators, high-quality optical cavities, or large magnetic fields are employed. Here we demonstrate the first room temperature, cavity-free, all-electric device where back-action damping exceeds internal loss, enabled by a mechanically compliant parallel-plate capacitor with a nanoscale plate separation and an aspect ratio exceeding 1,000. The device has 4 orders of magnitude lower insertion loss than a comparable commercial quartz crystal and achieves a position imprecision rivaling optical interferometers. 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.},

  abstract     = {We introduce a new all-electric platform, that strong couples light to mechanical motion
by ensuring that the external environmental coupling dominates over internal mechanical
dissipation. The system only has three everyday components: AC, DC, and a fip-chip, in which
a metallized silicon nitride membrane is fipped on top of the device under test. This everyday
electromechanical device can be operated at low or room temperature and has 10000× lower
insertion loss than a comparable commercial quartz crystal, achieves a position imprecision
matching state-of-the-art optical interferometer, and enables remote cooling of mechanical
motion. The spatial properties of higher order mechanical modes are a promising feature for
reconstructing unknown charge distributions.
