Ultra-stable transportable ultraviolet clock laser using cancellation between photo-thermal and photo-birefringence noise
Benjamin Kraus, Sofia Herbers, Constantin Nauk +3
Optical clocks require an ultra-stable laser to probe and precisely measure the frequency of the narrow-linewidth clock transition. We introduce a portable ultraviolet (UV) laser s…
Coordinated international comparisons between optical clocks connected via fiber and satellite links
Thomas Lindvall, Marco Pizzocaro, Rachel M. Godun +62
Optical clocks provide ultra-precise frequency references that are vital for international metrology as well as for tests of fundamental physics. To investigate the level of agreem…
International comparison of optical frequencies with transportable optical lattice clocks
International Clock, Oscillator Networking, Collaboration +37
Optical clocks have improved their frequency stability and estimated accuracy by more than two orders of magnitude over the best caesium microwave clocks that realise the SI second…
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…
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…
Experimental determination of the E2-M1 polarizability of the strontium clock transition
Sören Dörscher, Joshua Klose, Sarath Maratha Palli +1
To operate an optical lattice clock at a fractional uncertainty below , one must typically consider not only electric-dipole (E1) interaction between an atom and the latt…
