In-Yb Coulomb crystal clock with systematic uncertainty
H. N. Hausser, J. Keller, T. Nordmann +17
We present a scalable mixed-species Coulomb crystal clock based on the transition in In. Yb ions are co-trapped and used f…
Continuous optical generation of microwave signals for fountain clocks
Burghard Lipphardt, Patrick Walkemeyer, Michael Kazda +2
For the optical generation of ultrastable microwave signals for fountain clocks we developed a setup, which is based on a cavity stabilized laser and a commercial frequency comb. T…
Evaluation of a Sr optical clock with a direct measurement of the blackbody radiation shift and determination of the clock frequency
M. Steinel, H. Shao, M. Filzinger +7
We report on an evaluation of an optical clock that uses the transition of a single Sr ion as the reference. In con…
Improved limits for violations of local position invariance from atomic clock comparisons
R. Lange, N. Huntemann, J. M. Rahm +6
We compare two optical clocks based on the SD electric quadrupole (E2) and the SF electric octupole (E3)…
Optical frequency ratio of a single-ion clock and a lattice clock
Sören Dörscher, Nils Huntemann, Roman Schwarz +6
We report direct measurements of the frequency ratio of the 642 THz -- electric octupole transition in and the 429 THz…
Coherent suppression of tensor frequency shifts through magnetic field rotation
R. Lange, N. Huntemann, C. Sanner +4
We introduce a scheme to coherently suppress second-rank tensor frequency shifts in atomic clocks, relying on the continuous rotation of an external magnetic field during the free…
