Nonlinear calcium King plot constrains new bosons and nuclear properties
A. Wilzewski, L. I. Huber, M. Door +39
Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-Standard-Model (BSM) interactions that couple electrons and neutrons. However, it is cru…

Long-distance chronometric leveling with a portable optical clock
J. Grotti, I. Nosske, S. B. Koller +19
We have measured the geopotential difference between two locations separated by by comparison of two optical lattice clocks via an interferometric fiber link, uti…

International comparison of optical frequencies with transportable optical lattice clocks
International Clock, Oscillator Networking, Collaboration +37
Optical clocks have improved their frequency stability and estimated accuracy by more than two orders of magnitude over the best caesium microwave clocks that realise the SI second…
