A team of researchers in Austria has recently demonstrated that the world’s first nuclear clock could help answer whether the fine-structure constant changes over time. The scientists from the Vienna ...
For the first lecture in the Fall Physics Colloquium Series, Chuankun Zhang, a graduate student from the University of Colorado Boulder's physics department and a researcher at JILA, delivered an ...
A transportable ytterbium optical lattice clock has been commercially shipped, rapidly recommissioned, and tested against reference systems at the U.S. Naval Observatory, according to a recent arXiv ...
Nuclear effect The deformed shape of the ytterbium-173 nucleus (right) makes it possible to excite the clock transition with a relatively low-power laser. The same transition is forbidden (left) if ...
