Its a funny thing, but almost everything we measure in physics is related to an oscillator. For example, the second is defined by a fixed number of oscillations from a particular atom, undergoing a ...

John Reppy has come out of retirement to question the high-profile discovery of a new kind of quantum matter. The fourth time he is asked what the dental floss is for, John Reppy seems to hear. He ...

Scientists have developed a nanoscale spin-torsion oscillator that can measure miniscule amounts of twisting or torque in a metallic nanowire. The device can be used to uncover spin-dependent ...

This is a preview. Log in through your library . Abstract Supersolidity, the appearance of zero-viscosity flow in solids, was first indicated in helium-4 torsional oscillator (TO) experiments. In this ...

Physicists are reporting a major advance in the understanding of what appears to be a new state of matter -- supersolidity. Physicists have been manipulating solid helium so they can study its unusual ...

Cooled to temperatures just above absolute zero, solid helium starts to behave very oddly. But its 'supersolid' behaviour might just be the result of imperfections that change the bulk properties of ...

Gases are flighty and flitting and expand to fill any available space. Liquids will also mold themselves to whatever shape they occupy, from soda bottle to swimming pool. Solids, though, are steadfast ...

High-quality, single-crystal, ultra-cold solid helium exhibits supersolid behavior, suggesting that this frictionless solid flow is not a consequence of defects and grain boundaries in poor-quality, ...

The fourth time he is asked what the dental floss is for, John Reppy seems to hear. He picks up a pair of scissors, and starts snipping away at the plastic strands wound round the shiny ...
