Photoionization cross sections of ultracold Sr in P and S states at 390 nm and the resulting blue-detuned magic wavelength optical lattice clock constraints
Marcin Witkowski, Sławomir Bilicki, Marcin Bober +4
We present the measurements of the photoionisation cross sections of the excited P and S states of ultracold Sr atoms at 389.889 nm wavelength, which is the…
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…
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…
A noise-immune cavity-assisted non-destructive detection for an optical lattice clock in the quantum regime
G. Vallet, E. Bookjans, U. Eismann +3
We present and implement a non-destructive detection scheme for the transition probability readout of an optical lattice clock. The scheme relies on a differential heterodyne measu…
Test of special relativity using a fiber network of optical clocks
P. Delva, J. Lodewyck, S. Bilicki +28
Phase compensated optical fiber links enable high accuracy atomic clocks separated by thousands of kilometers to be compared with unprecedented statistical resolution. By searching…
Dual Hg-Rb magneto-optical trap
Marcin Witkowski, Bartlomiej Nagoorny, Rodolfo Munoz-Rodriguez +6
We present a two-species laser cooling apparatus capable of simultaneously collecting Rb and Hg atomic gases into a magneto-optical trap (MOT). The atomic sources, laser system, an…
