Hyperfine-mediated effects in a Lu $^{+}$ optical clock

Zhiqiang Zhang, K. J. Arnold, R. Kaewuam +2

We consider hyperfine-mediated effects for clock transitions in $^{176}$ Lu $^{+}$ . Mixing of fine structure levels due to the hyperfine interaction bring about modifications to Landé…

Branching fractions for $P_{3/2}$ decays in Ba $^{+}$

Zhiqiang Zhang, K. J. Arnold, S. R. Chanu +3

Branching fractions for decays from the $P_{3/2}$ level in $^{138}$ Ba $^{+}$ have been measured with a single laser-cooled ion. Decay probabilities to $S_{1/2}$ , $D_{3/2}$ and $D_{5/2…

Magic wavelength of the $^{138}$ Ba $^{+}$ $6 s^{2} S_{1/2} - 5 d^{2} D_{5/2}$ clock transition

S. R. Chanu, V. P. W. Koh, K. J. Arnold +5

The zero crossing of the dynamic differential scalar polarizability of the $S_{1/2} - D_{5/2}$ clock transition in $^{138}$ Ba $^{+}$ has been determined to be $459.1614 (28)$ THz. Toget…

Suppressing inhomogeneous broadening in a lutetium multi-ion optical clock

Ting Rei Tan, Rattakorn Kaewuam, Kyle J. Arnold +4

We demonstrate precision measurement and control of inhomogeneous broadening in a multi-ion clock consisting of three $^{176}$ Lu $^{+}$ ions. Microwave spectroscopy between hyperfine…
