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…

Guidelines for developing optical clocks with $1 0^{- 18}$ fractional frequency uncertainty

Moustafa Abdel-Hafiz, Piotr Ablewski, Ali Al-Masoudi +42

There has been tremendous progress in the performance of optical frequency standards since the first proposals to carry out precision spectroscopy on trapped, single ions in the 19…

Absolute frequency measurement of the $^{2}$ S $_{1/2} \to^{2}$ F $_{7/2}$ optical clock transition in $^{171}$ Yb $^{+}$ with an uncertainty of $4 \times 1 0^{- 16}$ using a frequency link to International Atomic Time

Charles F. A. Baynham, Rachel M. Godun, Jonathan M. Jones +8

The highly forbidden $^{2}$ S $_{1/2} \to^{2}$ F $_{7/2}$ electric octupole transition in $^{171}$ Yb $^{+}$ is a potential candidate for a redefinition of the SI second. We present a…

A method of state-selective transfer of atoms between microtraps based on the Franck-Condon Principle

A. B. Deb, G. Smirne, R. M. Godun +1

We present a method of transferring a cold atom between spatially separated microtraps by means of a Raman transition between the ground motional states of the two traps. The inter…
