High-accuracy multi-ion spectroscopy with mixed-species Coulomb crystals
J. Keller, H. N. Hausser, I. M. Richter +14
Multi-ion optical clocks offer the possibility of overcoming the low signal-to-noise ratio of single-ion clocks, while still providing low systematic uncertainties. We present simu…

Controlling systematic frequency uncertainties at the level in linear Coulomb crystals
J. Keller, T. Burgermeister, D. Kalincev +5
Trapped ions are ideally suited for precision spectroscopy, as is evident from the remarkably low systematic uncertainties of single-ion clocks. The major weakness of these clocks…
