Par Jun Ye.
\nThe next clocks will be the measure of everything.<\/p>\n
By Jun Ye. A physicist at JILA, National Institute of Standards and Technology, and at the University of Colorado at Boulder, Jun Ye has focused his research mostly on ultracold atoms, ultracold molecules and laser-based precision measurement. Together with his team, he has built the most precise atomic clock in the world thus far, with variation of less than one second in 15 billion years. Like a universal tool, the next generation of such clocks could help unravel more and more mysteries of the Universe, both in quantum physics and cosmology, leading hopefully to a new physics.<\/p>\n Physicien au JILA, National Institute of Standards and Technology et \u00e0 l\u2019universit\u00e9 du Colorado \u00e0 Boulder, Jun Ye se consacre principalement \u00e0 l\u2019\u00e9tude des atomes ultra-froids, des mol\u00e9cules ultra-froides et aux mesures laser de haute pr\u00e9cision.
