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…
Measurement of the Electric Dipole Moment of Yb Atoms in an Optical Dipole Trap
T. A. Zheng, Y. A. Yang, S. -Z. Wang +4
The permanent electric dipole moment (EDM) of the Yb atom is measured with atoms held in an optical dipole trap (ODT). By enabling a cycling transition that is si…
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…
Measurement of the Hyperfine Quenching Rate of the Clock Transition in Yb
C. -Y. Xu, J. Singh, J. C. Zappala +8
We report the first experimental determination of the hyperfine quenching rate of the transition in Yb with nuclear spin $…
Radiometric 81Kr dating identifies 120,000 year old ice at Taylor Glacier, Antarctica
Christo Buizert, Daniel Baggenstos, Wei Jiang +8
We present the first successful 81Kr-Kr radiometric dating of ancient polar ice. Krypton was extracted from the air bubbles in four ~350 kg polar ice samples from Taylor Glacier in…
