International Optical Clock Comparison Using the European Optical Fiber Network
Marco Pizzocaro, Clara Zyskind, Anne Amy-Klein +41
Optical clocks have achieved remarkable estimated fractional frequency uncertainties reaching the level and below, enabling applications in fundamental physics, general…
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…
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…
A Cs-Based Optical Frequency Measurement Using Cross-Linked Optical and Microwave Oscillators
Chr. Tamm, N. Huntemann, B. Lipphardt +5
We describe a measurement of the frequency of the 2S1/2(F = 0) - 2D3/2(F' = 2) transition of 171Yb+ at the wavelength 436 nm (frequency 688 THz), using a single Yb+ ion confined in…
Laboratory Limits on Temporal Variations of Fundamental Constants: An Update
E. Peik, B. Lipphardt, H. Schnatz +3
Precision comparisons of different atomic frequency standards over a period of a few years can be used for a sensitive search for temporal variations of fundamental constants. We p…
