Terrestrial Very-Long-Baseline Atom Interferometry: Summary of the Second Workshop
Adam Abdalla, Mahiro Abe, Sven Abend +307
This summary of the second Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) Workshop provides a comprehensive overview of our meeting held in London in April 2024, build…
Search for fast-oscillating fundamental constants with space missions
Dmitry Budker, Joshua Eby, Marianna S. Safronova +1
While it is possible to estimate the dark matter density at the Sun distance from the galactic center, this does not give information on actual dark matter density in the Solar sys…
Fine-structure constant sensitivity of the Th-229 nuclear clock transition
Kjeld Beeks, Georgy A. Kazakov, Fabian Schaden +12
State-resolved laser spectroscopy at the 10 precision level recently reported in :2406.18719 determined the fractional change in nuclear quadrupole moment between th…
Pr10+ as a candidate for a high-accuracy optical clock for tests of fundamental physics
S. G. Porsev, C. Cheung, M. S. Safronova +4
We propose In-like Pr10+ as a candidate for the development of a high-accuracy optical clock with high sensitivity to a time variation of the fine-structure constant, (\dot alpha}/…
A clock with systematic uncertainty
Alexander Aeppli, Kyungtae Kim, William Warfield +2
We report an optical lattice clock with a total systematic uncertainty of in fractional frequency units, representing the lowest uncertainty of any clock to d…
Bosenovae with Quadratically-Coupled Scalars in Quantum Sensing Experiments
Jason Arakawa, Muhammad H. Zaheer, Joshua Eby +2
Ultralight dark matter (ULDM) particles of mass can form boson stars in DM halos. Collapse of boson stars leads to explosive bosenova emission of copious r…
Coherent excitation of a Hz scale optical magnetic quadrupole transition
V. Klüsener, S. Pucher, D. Yankelev +7
We report on the coherent excitation of the ultranarrow - magnetic quadrupole transition in . By confining atoms in a state in…
High-Precision Transition Energy Measurements of Neon-like Fe XVII Ions
Chintan Shah, Moto Togawa, Marc Botz +15
We improve by a factor of 4-20 the energy accuracy of the strongest soft X-ray transitions of Fe XVII ions by resonantly exciting them in an electron beam ion trap with a monochrom…
