Extreme-ultraviolet spectroscopy using quantum logic: a feasibility study for the 1S-2S transition in singly-ionized helium
A. Martínez de Velasco, V. P. J. Barbé, E. L. Gründeman +11
Extreme-ultraviolet (XUV) spectroscopy represents an important new direction in precision physics, with potential applications ranging from the metrology of fundamental constants t…
Laser Excitation of the 1S-2S Transition in Singly-Ionized Helium
Elmer L. Gründeman, Vincent Barbé, Andrés Martínez de Velasco +6
Precision laser spectroscopy in the extreme ultraviolet of the 1S-2S two-photon transition in singly-ionized helium is a promising route for tests of fundamental physics. We demons…
Demonstration of Ramsey-Comb Precision Spectroscopy in Xenon at Vacuum Ultraviolet Wavelengths Produced with High-Harmonic Generation
L. S. Dreissen, C. Roth, E. L. Gründeman +3
The remarkable progress in the field of laser spectroscopy induced by the invention of the frequency-comb laser has enabled many new high-precision tests of fundamental theory and…
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…
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…
Atomically thin semiconductors as nonlinear mirrors
Sina Zeytinoglu, Charlaine Roth, Sebastian Huber +1
We show that a transition metal dichalcogenide monolayer with a radiatively broadened exciton resonance would exhibit perfect extinction of a transmitted field. This result holds f…
