Frequency ratio of an $^{115}$ In $^{+}$ ion clock and a $^{87}$ Sr optical lattice clock

Nozomi Ohtsubo, Ying Li, Nils Nemitz +4

We report on the first frequency ratio measurement of an $^{115}$ In+ single ion clock and a $^{87}$ Sr optical lattice clock. A hydrogen maser serves as a reference oscillator to me…

Frequency measurement of the clock transition of an indium ion sympathetically-cooled in a linear trap

Nozomi Ohtsubo, Ying Li, Kensuke Matsubara +2

We report frequency measurement of the clock transition in an 115In+ ion sympathetically-cooled with Ca+ ions in a linear rf trap. The Ca+ ions are used as a probe of the external…
