The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

Heat is not supposed to behave like this. In everyday life, warmth seeps and diffuses, spreading from hot to cold in a slow, smearing process that never looks anything like a crisp sound wave. Yet ...

Using a newly devised technology, scientists can move small objects without touching them, meaning we're one step closer to Jedi being real.

“Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection ...

Future wireless networks will need to process far more data across a wider range of frequencies than today’s systems. This ...

Helium leaks are hard to detect, since it is odorless, colorless, tasteless, and does not react with other chemical substances. In Applied Physics Letters, by AIP Publishing, researchers from Nanjing ...

The magical acoustic secrets of a famous cave known as the "Devil's Church" have been revealed by researchers. The Devil's Cave, also known Pirunkirkko, is situated in the Koli mountain range in ...

When exposed to stress and strain, materials can display a wide range of different properties. By using sound waves, scientists have begun to explore fundamental stress behaviors in a crystalline ...
