One of the most profound open questions in modern physics is: "Is gravity quantum?" The other fundamental ...

A research team at ETH Zurich led by Dr. Matteo Fadel recently introduced a new approach to realize quantum squeezing in a nonlinear mechanical oscillator. This approach, outlined in a paper ...

One of those was the mechanical oscillator, and [Integza] had a go at replicating the device himself. (Video, embedded below the break.) Initial attempts to reproduce the technology using 3D ...

The conversion occurs through the coupling between light and a mechanical oscillator, without interruption by thermal mechanical vibrations. Using tiny radiation pressure forces -- generated each ...

Zenith has re-engineered the mechanical watch movement by inventing a new single-piece oscillator that replaces the traditional hairspring/balance wheel assembly. It oscillates at a frequency five ...

The proposal involves a tiny mechanical oscillator built by John Teufel and colleagues at the National Institute of Standards and Technology in Colorado. That oscillator is an aluminium disc 15 μm ...

One of LIGO’s four 40-kg mirrors cooled during the experiment. Together, these mirrors form a mechanical oscillator of 10-kg — which the team cooled down in their experiment. Caltech/MIT/LIGO ...
