Continuous-wave 148.4-nm generation in strontium tetraborate for nuclear absorption spectroscopy
Hanlin Wang, Zhouzhi Tan, Conghui Huang +13
Continuous-wave light near 148.4 nm enables direct absorption spectroscopy of the thorium-229 nuclear transition. We demonstrate single-pass frequency doubling in strontium tetrabo…
Validating a lutetium frequency reference
Kyle J. Arnold, Scott Bustabad, Qin Qichen +3
We review our progress in developing a frequency reference with singly ionized lutetium and give estimates of the levels of inaccuracy we expect to achieve in the near future with…
Lu clock comparison at the level via correlation spectroscopy
Zhang Zhiqiang, Kyle J. Arnold, Rattakorn Kaewuam +1
We experimentally demonstrate agreement between two Lu frequency references using correlation spectroscopy. From a comparison at different magnetic fields, we obtain a…
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 Lu. Mixing of fine structure levels due to the hyperfine interaction bring about modifications to Landé…
Precision measurement of the and quadrupole moments in Lu
R. Kaewuam, T. R. Tan, Zhiqiang Zhang +3
Precision measurements of the Lu and quadrupole moments have been carried out giving and , respect…
Branching fractions for decays in Ba
Zhiqiang Zhang, K. J. Arnold, S. R. Chanu +3
Branching fractions for decays from the level in Ba have been measured with a single laser-cooled ion. Decay probabilities to , and $D_{5/2…
Hyperfine averaging by dynamic decoupling in a multi-ion lutetium clock
R. Kaewuam, T. R. Tan, K. J. Arnold +3
We propose and experimentally demonstrate a scheme which effects hyperfine averaging during a Ramsey interrogation of a clock transition. The method eliminates the need to average…
Magic wavelength of the Ba clock transition
S. R. Chanu, V. P. W. Koh, K. J. Arnold +5
The zero crossing of the dynamic differential scalar polarizability of the clock transition in Ba has been determined to be 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 Lu ions. Microwave spectroscopy between hyperfine…
Measurements of the branching ratios for decays in Ba
K. J. Arnold, S. R. Chanu, R. Kaewuam +5
Measurement of the branching ratios for decays to and in Ba are reported with the decay probability from to measu…
Dicke model simulation via cavity-assisted Raman transitions
Zhang Zhiqiang, Chern Hui Lee, Ravi Kumar +5
The Dicke model is of fundamental importance in quantum mechanics for understanding the collective behaviour of atoms coupled to a single electromagnetic mode. In this paper, we de…
