  text: 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.

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

  text: Arrays of Josephson junctions are governed by a competition between superconductivity
    and repulsive Coulomb interactions, and are expected to exhibit diverging low-temperature
    resistance when interactions exceed a critical level. Here we report a study of
    the transport and microwave response of Josephson arrays with interactions exceeding
    this level. Contrary to expectations, we observe that the array resistance drops
    dramatically as the temperature is decreased—reminiscent of superconducting behaviour—and
    then saturates at low temperature. Applying a magnetic field, we eventually observe
    a transition to a highly resistive regime. These observations can be understood
    within a theoretical picture that accounts for the effect of thermal fluctuations
    on the insulating phase. On the basis of the agreement between experiment and
    theory, we suggest that apparent superconductivity in our Josephson arrays arises
    from melting the zero-temperature insulator.

  text: We present conductance-matrix measurements in long, three-terminal hybrid
    superconductor-semiconductor nanowires, and compare with theoretical predictions
    of a magnetic-field-driven, topological quantum phase transition. By examining
    the nonlocal conductance, we identify the closure of the excitation gap in the
    bulk of the semiconductor before the emergence of zero-bias peaks, ruling out
    spurious gap-closure signatures from localized states. We observe that after the
    gap closes, nonlocal signals and zero-bias peaks fluctuate strongly at both ends,
    inconsistent with a simple picture of clean topological superconductivity.
