Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a compact atomic clock design that relies on cold rubidium atoms instead of the usual hot atoms, a switch that promises improved precision and stability.
Using the new approach, which harnesses the quantum interference of matter waves, the team was able to cool a sample of already - cold Rubidium down close to the fundamental temperature limit of laser cooling.
Not exact matches
Cornell and Wieman were trying to cool a puff of rubidium gas to within a few billionths of a degree of absolute zero — colder than any place in nature, even the 2.73 kelvins of space.
To this end a cloud of extremely cold (i.e. extremely slow) rubidium atoms is loaded into an optical lattice, generated by crosswise superposition of standing laser waves.
NIST's cold - atom clock relies on about 1 million rubidium atoms held in a small glass vacuum chamber.
