PORTLAND, Ore. — A candidate to be the next-generation atomic clock is based on the heavy metal strontium and uses a laser lattice to suspend super-cooled atoms. The result was a 430-THz time ...

Science rarely hands us an image that rewires intuition as much as it satisfies curiosity. But one faint, floating ...

BOULDER, Colo.- A next-generation atomic clock that tops previous records for accuracy in clocks based on neutral atoms has been demonstrated by physicists at JILA, a joint institute of the Commerce ...

Having good neighbors can be very valuable—even in the atomic world. A team of Amsterdam physicists was able to determine an important property of strontium atoms, a highly useful element for modern ...

Small clouds of strontium atoms (blue) and rubidium atoms (red) are trapped together. The well-known properties of rubidium can be used to calibrate the applied magnetic field very precisely, which in ...
