High-Precision Ramsey-Comb Spectroscopy Based on High-Harmonic Generation
L. S. Dreissen, C. Roth, E. L. Gründeman +3
High-harmonic generation (HHG) is widely used for up-conversion of amplified (near) infrared ultrafast laser pulses to short wavelengths. We demonstrate that Ramsey-comb spectrosco…
Laser Trapping of Circular Rydberg Atoms
R. G. Cortiñas, M. Favier, B. Ravon +5
Rydberg atoms are remarkable tools for quantum simulation and computation. They are the focus of an intense experimental activity mainly based on low-angular-momentum Rydberg state…
Paving the way for fundamental physics tests with singly-ionized helium
J. J. Krauth, L. S. Dreissen, C. Roth +4
High-precision laser spectroscopy of atomic hydrogen has led to an impressive accuracy in tests of bound-state quantum electrodynamics (QED). At the current level of accuracy many…
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…
