Ultra-stable optical clock with two cold-atom ensembles

January 01, 2017

Author(s):

Marco Schioppo, Roger C. Brown, William F. McGrew, Nathan M. Hinkley, Robert J. Fasano, Kyle P. Beloy, Gianmaria Milani, Daniele Nicolodi, Jeffrey A. Sherman, Nate B. Phillips, Christopher W. Oates, Andrew D. Ludlow

Atomic clocks based on optical transitions are the most stable, and therefore precise, timekeepers available. These clocks operate by alternating intervals of...

Optical Lattice Clocks

January 01, 2015

Author(s):

Andrew D. Ludlow, Christopher W. Oates

Here we introduce and give a basic description of optical lattice clocks. We also briefly describe recent advances in these atomic frequency standards, looking...

Atomic Clock with 1x10^-18 Room-Temperature Blackbody Stark Uncertainty

December 31, 2014

Author(s):

Kyle P. Beloy, Nathan M. Hinkley, Nate B. Phillips, Jeffrey A. Sherman, Marco Schioppo, John H. Lehman, Ari D. Feldman, Leonard M. Hanssen, Christopher W. Oates, Andrew D. Ludlow

The Stark shift due to blackbody radiation (BBR) is a key factor limiting the performance of many atomic frequency standards, with the BBR environment inside...

Optical Atomic Clocks

December 01, 2013

Author(s):

Christopher W. Oates, N Poli, P. Gill, G.M. Tino

In the last ten years extraordinary results in time and frequency metrology have been demonstrated. Frequency stabilization techniques for continous wave...
