An $^{27}$ Al $^{+}$ quantum-logic clock with systematic uncertainty below $1 0^{- 18}$

S. M. Brewer, J. -S. Chen, A. M. Hankin +5

We describe an optical atomic clock based on quantum-logic spectroscopy of the $^{1}$ S $_{0}$ $\leftrightarrow$ $^{3}$ P $_{0}$ transition in $^{27}$ Al $^{+}$ with a systematic uncertainty of…

Hyperfine-mediated electric quadrupole shifts in Al $^{+}$ and In $^{+}$ ion clocks

K. Beloy, D. R. Leibrandt, W. M. Itano

We evaluate the electric quadrupole moments of the $^{1} S_{0}$ and $^{3} P_{0}$ clock states of $^{27}$ Al $^{+}$ and $^{115}$ In $^{+}$ . To capture all dominant contributions, our analysis…

Sympathetic ground state cooling and time-dilation shifts in an $^{27} Al^{+}$ optical clock

J. -S. Chen, S. M. Brewer, C. W. Chou +3

We report on Raman sideband cooling of $^{25} Mg^{+}$ to sympathetically cool the secular modes of motion in a $^{25} Mg^{+}$ - $^{27} Al^{+}$ two-ion pair to near th…
