Evaluation of trap-induced systematic frequency shifts for a multi-ion optical clock at the $1 0^{- 19}$ level

J. Keller, T. Burgermeister, D. Kalincev +2

In order to improve the short-term stability of trapped-ion optical clocks, we are developing a frequency standard based on $^{115}$ In $^{+}$ / $^{172}$ Yb $^{+}$ Coulomb crystals…

Precise determination of micromotion for trapped-ion optical clocks

J. Keller, H. L. Partner, T. Burgermeister +1

As relative systematic frequency uncertainties in trapped-ion spectroscopy are approaching the low $1 0^{- 18}$ range, motional frequency shifts account for a considerable fraction o…
