MIT Laser-cooling brings Coin-sized Object to near Absolute Zero

Apr 9 2007, 6:00am CDT | by Luigi Lugmayr

MIT researchers have cooled a coin-sized object to within one degree of absolute zero with a laser-cooling technique.

This study marks the coldest temperature ever reached by laser-cooling of an object of that size, and the technique holds promise that it will experimentally confirm, for the first time, that large objects obey the laws of quantum mechanics just as atoms do. To see quantum effects in large objects, they must be cooled to near absolute zero.
The MIT researchers and colleagues at Caltech and the Albert Einstein Institute in Germany will report their findings in an upcoming issue of Physical Review Letters.
