Physicists have demonstrated all the ingredients of a nuclear clock — a device that keeps time by measuring tiny energy shifts inside an atomic nucleus. Such clocks could lead to vast improvements in ...

What do you get when you put a nuclear physicist, an optical physicist and a crystal-growing maestro together in a laboratory? This is not the beginning of a bad joke, but the starting point for ...

The clock is so reliable that it would be off by less than a second if it had started running 100 million years ago, researchers say. A new atomic clock is one of the world’s best timekeepers, ...

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 ...
