  • Abstract
    Presents a new technique for compensating frequency drift in a trapped ion frequency standard by simultaneously holding 171Yb+ and 199Hg+. Environmental perturbations affect the hyperfine splitting of these two ions very differently. By monitoring the changes in the frequency difference between their hyperfine levels we can compensate for some of the frequency drift due to changes in external perturbations
