Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct ...

NIST/JILA Fellow Jun Ye works on JILA's strontium clock. Ye has been instrumental in making the clock 50 percent more accurate than it was a year ago. Physicists have measured and controlled seemingly ...

Intersecting laser beams create "optical tubes" to pack atoms close together, enhancing their interaction and the performance of JILA's strontium atomic clock. Image by Richard B. Baxley/JILA In a ...
