JILA Physicists Achieve Elusive "Evaporative Cooling" of Molecules
December 19, 2012
Achieving a goal considered nearly impossible, physicists at JILA have chilled a gas of molecules to very low temperatures by adapting the familiar process by which a hot cup of coffee cools. Evaporative cooling has long been used to cool atoms, at JILA and elsewhere, to extraordinarily low temperatures. The process was used at JILA in 1995 to create the Bose-Einstein condensate. The latest demonstration marks the first time evaporative cooling has been achieved with molecules.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
