This is a strontium atomic clock operating at JILA, University of Colorado. Laser light is used to cool and manipulate the atoms for optimal operation of the clock. Carefully designed magnetic ...

The strontium-based atomic clock also uses lasers to confine and cool atoms, but the natural resonant frequency is locked in with a new measurement methodology called the “optical frequency comb.” The ...

The JILA clock used in the latest experiments contains about 2,000 strontium atoms cooled to temperatures of a few microKelvin (a few millionths of a degree above absolute zero) and trapped in ...

The clock they demonstrated is not the full nuclear clock experience, but the first steps in that direction. The strontium clock at JILA at the National Institute of Standards & Technology is ...

The clock – developed by JILA, a joint physics institute of the University of Colorado at Boulder and NIST uses “strontium atoms held in a lattice of laser light” to achieve its precision ...

JILA's strontium clock is one of several next-generation atomic clocks under development around the world. These experimental clocks are based on a variety of different atoms and designs, from ...

Pairs of extremely cold strontium atoms have been used to make the most accurate molecular clock yet. It could be used to detect new forces and test some of Albert Einstein’s ideas about gravity.

JILA scientists demonstrated the new approach using their experimental clock made of about 4,000 strontium atoms. Instead of loading the atoms into a stack of pancake-shaped optical traps as in their ...

The National Institute of Standards and Technology (NIST) has announced that a new experimental atomic clock based on a single mercury atom is now at least five times more precise than NIST-F1 ...

A new experiment paired a ytterbium-based atomic clock with two others that used aluminum and strontium atoms, respectively, to create an even more accurate measure of time. Burrus / NIST ...

Advanced atomic clock makes a better dark matter detector Date: November 12, 2020 Source: National Institute of Standards and Technology (NIST) Summary: Researchers have used a state-of-the-art ...
