Using a laser-cooling technique that could one day allow scientists to observe quantum behavior in large objects, MIT researchers have cooled a coin-sized object to within one degree of absolute zero.

The LIGO gravitational wave observatory in the United States is so sensitive to vibrations it can detect the tiny ripples in space-time called gravitational waves. These waves are caused by colliding ...

Within quantum mechanics, there has been an observable limit (the quantum backaction limit) on how low you can cool an object experimentally. Up until very recently, that limit had not been challenged ...

A team of physicists say they’ve managed to nearly freeze the motion of atoms across four suspended mirrors. It’s a mind-twisting feat that strains the very definitions of seemingly simple words like ...

The absolute lowest temperature possible is -273.15 degrees Celsius. It is never possible to cool any object exactly to this temperature – one can only approach absolute zero. This is the third law of ...

Absolute zero is often thought to be the coldest temperature possible. But now researchers show they can achieve even lower temperatures for a strange realm of "negative temperatures." Oddly, another ...

Scientists cooled LEGOs to nearly absolute zero—and hope to one day incorporate a LEGO-style material into a quantum computer. Objects that transfer heat slowly form useful components in technologies ...

A new type of cooling relies on an exotic quantum mechanical property rather than putting objects into cold environments like refrigerators – and it might one day help us chill things to temperatures ...
