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…
Long term measurement of the Sr clock frequency at the limit of primary Cs clocks
R. Schwarz, S. Dörscher, A. Al-Masoudi +7
We report on a series of 42 measurements of the transition frequency of the 429~THz (5s)~S--(5s5p)~P line in Sr taken over three years from 2017 to 2019.…
