An extrapolation method for polarizability assessments of ion-based optical clocks
K. J. Arnold, M. D. Barrett
We present a numerical method for extrapolating polarizability measurements to dc as done in the assessment of blackbody radiation shifts for ion-based clocks. The method explicitl…

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…

Enhanced micromotion compensation using a phase modulated light field
K. J. Arnold, N. Jayjong, M. L. D. Kang +4
We investigate sideband spectroscopy of a trapped ion using a probe laser phase modulated at the trap drive frequency. The enhanced sensitivity of our technique over traditional si…
