A solid-state nuclear clock based on VUV absorption spectroscopy of Th
Pengfei Wang, Xu-Fei Yin, Hanlin Wang +21
We demonstrate sustained operation of a solid-state thorium-229 nuclear clock using continuous-wave absorption at 148.4 nm. In a crystal, we reso…
A thorium-229 optical nuclear clock with feedback loop
L. Toscani De Col, T. Riebner, I. Morawetz +25
The laser-accessible nuclear transition in the thorium-229 isotope has been identified as a promising candidate for the realization of an optical nuclear clock. Such a nuclear cloc…
Fluorescence and Relaxation Dynamics of Cesium in Argon Matrices: Multiple Trapping Sites and Host-Guest Interactions
S. Lahs, H. Dinesan, S. Mahapatra +6
We investigate the fluorescence and relaxation dynamics of Cs atoms embedded in a cryogenic argon matrix using spectroscopy measurements combined with diatomic-in-molecule (DIM) si…
Continuous-wave laser absorption spectroscopy of the Thorium-229 nucleus
I. Morawetz, T. Riebner, L. Toscani De Col +17
A low-energy nuclear transition in the isotope thorium-229 has been excited in thorium-doped crystals with laser light. This opens the perspective towards a highly stable and robus…
Atomic Observables Induced by Cosmic Fields
Sebastian Lahs, Daniel Comparat, Fiona Kirk +1
The existence of cosmic fields made from yet unknown light bosons is predicted in many extensions to the Standard Model. They are especially of interest as possible constituents of…
Demonstration of deuterium's enhanced sensitivity to symmetry violations governed by the Standard-Model Extension
Amit Nanda, Daniel Comparat, Olivier Dulieu +5
We have performed hyperfine spectroscopy of two transitions in ground-state deuterium and searched for violations of CPT and Lorentz symmetry that would manifest as sidereal variat…
Polarizabilities as Probes for P, T, and PT Violation
Sebastian Lahs, Daniel Comparat
Searches for violations of the fundamental symmetries of parity P and time reversal T in atomic and molecular systems provide a powerful tool for precise measurements of the physic…
CPT and Lorentz symmetry tests with hydrogen using a novel in-beam hyperfine spectroscopy method applicable to antihydrogen experiments
Lilian Nowak, Chloe Malbrunot, Martin C. Simon +8
We present a Rabi-type measurement of two ground-state hydrogen hyperfine transitions performed in two opposite external magnetic field directions. This puts first constraints at t…
Cesium atoms in cryogenic argon matrix
Thomas Battard, Sebastian Lahs, Claudine Crépin +1
This paper presents both experimental and theoretical investigations into the spectroscopy of dilute cesium (Cs) atoms within a solid argon (Ar) matrix at cryogenic temperatures. T…
