JILA physicists discover 'quantum droplet' in semiconductor

JILA physicists used an ultrafast laser and help from German theorists to discover a new semiconductor quasiparticle—a handful of smaller particles that briefly condense into a liquid-like droplet.

JILA strontium atomic clock sets new records in both precision and stability

Heralding a new age of terrific timekeeping, a research group led by a National Institute of Standards and Technology (NIST) physicist has unveiled an experimental strontium atomic clock that has set new world records for both precision and stability-- key metrics for the performance of a clock.
