January 11, 2013

Holger Müller, guest scientist with the Chemical Sciences Division, led a team of Berkeley scientists in the development of a “Compton frequency clock,” a special clock that can measure time on the basis of the mass of a single atomic or even subatomic particle. The clock, which uses an atom interferometer developed by Energy Secretary Steve Chu while at Stanford, holds promise not only for ultraprecise measurements of mass and time, but also for such exotic applications as testing Einstein’s general theory of relativity, or the effects of gravity on antimatter.
