Search for spin-dependent gravitational interactions at the Earth range
Shaobo Zhang, Zengli Ba, Denghui Ning +3
Among the four fundamental forces, only gravity does not couple to particle spins according to the general theory of relativity. We test this principle by searching for an anomalou…
Search for topological defect dark matter with a global network of optical magnetometers
Samer Afach, Ben C. Buchler, Dmitry Budker +46
Ultralight bosons such as axion-like particles are viable candidates for dark matter. They can form stable, macroscopic field configurations in the form of topological defects that…
Enhancement of the and count rates by optical pumping
Z. -Y. Zhang, F. Ritterbusch, W. -K. Hu +7
We report an increase of up to 60% on the count rates of the rare and isotopes in the Atom Trap Trace Analysis method by enhancing the product…
Kr dating at the Guliya ice cap, Tibetan Plateau
Lide Tian, Florian Ritterbusch, Ji-Qiang Gu +5
We present radiometric Kr dating results for ice samples collected at the outlets of the Guliya ice cap in the western Kunlun Mountains of the Tibetan Plateau. This first ap…
Using 81Kr and Noble Gases to Characterize and Date Groundwater and Brines in the Baltic Artesian Basin on the One-Million-Year Timescale
Christoph Gerber, Rein Vaikmäe, Werner Aeschbach +12
Analyses for Kr and noble gases on groundwater from the deepest aquifer system of the Baltic Artesian Basin (BAB) were performed to determine groundwater ages and uncover th…
Improved limit on the Ra electric dipole moment
Michael Bishof, Richard H. Parker, Kevin G. Bailey +10
Background: Octupole-deformed nuclei, such as that of Ra, are expected to amplify observable atomic electric dipole moments (EDMs) that arise from time-reversal and parity-…
