Sub-part-per-trillion test of the Standard Model with atomic hydrogen
Lothar Maisenbacher, Vitaly Wirthl, Arthur Matveev +4
Quantum electrodynamics (QED), the first relativistic quantum field theory, describes light-matter interactions at a fundamental level and is one of the pillars of the Standard Mod…

Precision spectroscopy of the 2S-P transitions in atomic hydrogen
Lothar Maisenbacher
Precision spectroscopy of atomic hydrogen is an important way to test bound-state quantum electrodynamics (QED), one of the building blocks of the Standard Model. In its simplest f…

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…
