We report a two-detector measurement of the propagation speed of neutrinos over a baseline of 734 km. The measurement was made with the NuMI beam at Fermilab between the near and far MINOS detectors. The fractional difference between the neutrino spe

We experimentally investigate an optical clock based on $^{171}$Yb ($I=1/2$) atoms confined in an optical lattice. We have evaluated all known frequency shifts to the clock transition, including a density-dependent collision shift, with a fractional

A novel, all-digital measurement system has been developed at the National Institute of Standards and Technology (NIST) as an alternative to the traditional analog approach to measuring time differences between the outputs of atomic standards used in
