Improved limits on the coupling of ultralight bosonic dark matter to photons from optical atomic clock comparisons
M. Filzinger, S. Dörscher, R. Lange +6
We present improved constraints on the coupling of ultralight bosonic dark matter to photons based on long-term measurements of two optical frequency ratios. In these optical clock…
An Optical Atomic Clock Based on a Highly Charged Ion
Steven A. King, Lukas J. Spieß, Peter Micke +9
Optical atomic clocks are the most accurate measurement devices ever constructed and have found many applications in fundamental science and technology. The use of highly charged i…
Universal formalism for data sharing and processing in clock comparison networks
Jérôme Lodewyck, Rodolphe Le Targat, Paul-Eric Pottie +3
We present a mathematical framework adapted to the comparison of atomic clocks remotely connected by a complex network of optical or microwave links. This framework facilitates the…
Coherent laser spectroscopy of highly charged ions using quantum logic
P. Micke, T. Leopold, S. A. King +6
Precision spectroscopy of atomic systems is an invaluable tool for the advancement of our understanding of fundamental interactions and symmetries. Recently, highly charged ions (H…
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 excitation of the highly forbidden electric octupole transition in Yb
Henning A. Fürst, Chih-Han Yeh, Dimitri Kalincev +7
We report on the first coherent excitation of the highly forbidden electric octupole (E3) transition in a single trapped Yb ion, an…
