Searching for dark matter with an unequal delay interferometer
Etienne Savalle, Aurelien Hees, Florian Frank +6
We propose a new type of experiment that compares the frequency of a clock (an ultra-stable optical cavity in this case) at time to its own frequency some time earlier, b…
Two-Branch Fiber Link for International Clock Networks
Dan Xu, Etienne Cantin, Florian Frank +6
We present our work on realizing two-branch fiber links enabling multiple-partner clock comparisons in Europe. We report in detail on the setup connecting two long haul links, and…
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…
Novel approaches to dark-matter detection using space-time separated clocks
Etienne Savalle, Benjamin M. Roberts, Florian Frank +5
We discuss the theoretical analysis and interpretation of space-time separated clock experiments in the context of a space-time varying scalar field that is non-universally coupled…
