Direct comparisons of European primary and secondary frequency standards via satellite techniques
F. Riedel, A. Al-Masoudi, E. Benkler +46
We carried out a 26-day comparison of five simultaneously operated optical clocks and six atomic fountain clocks located at INRIM, LNE-SYRTE, NPL and PTB by using two satellite-bas…
A pyramid MOT with integrated optical cavities as a cold atom platform for an optical lattice clock
William Bowden, Richard Hobson, Ian R. Hill +6
We realize a two-stage, hexagonal pyramid magneto-optical trap (MOT) with strontium, and demonstrate loading of cold atoms into cavity-enhanced 1D and 2D optical lattice traps, all…
Search for transient variations of the fine structure constant and dark matter using fiber-linked optical atomic clocks
B. M. Roberts, P. Delva, A. Al-Masoudi +51
We search for transient variations of the fine structure constant using data from a European network of fiber-linked optical atomic clocks. By searching for coherent variations in…
Guidelines for developing optical clocks with 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…
