JILA's 3D Quantum Gas Clock Sets Precision Record, Aids Dark Matter Hunt
Scientists at JILA and NIST have built a three-dimensional quantum gas clock using strontium atoms that sets a new quality factor record and achieves errors of just 3.5 parts in 10 quintillion. The design, the first to use a degenerate Fermi gas, could improve timekeeping and aid the search for dark matter.
