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…
Yb optical clock with systematic uncertainty and absolute frequency measurements
Alexandra Tofful, Charles F. A. Baynham, E. Anne Curtis +9
A full evaluation of the uncertainty budget for the ytterbium ion optical clock at the National Physical Laboratory (NPL) was performed on the electric octupole (E3) $^2\mathrm{S}_…
Analysis of atomic-clock data to constrain variations of fundamental constants
Nathaniel Sherrill, Adam O. Parsons, Charles F. A. Baynham +13
We present a new framework to study the time variation of fundamental constants in a model-independent way. Model independence implies more free parameters than assumed in previous…
Measuring the stability of fundamental constants with a network of clocks
G. Barontini, L. Blackburn, V. Boyer +41
The detection of variations of fundamental constants of the Standard Model would provide us with compelling evidence of new physics, and could lift the veil on the nature of dark m…
