Improved limit on the permanent electric dipole moment of 199Hg
W. C. Griffith, M. D. Swallows, T. H. Loftus +3
We report the results of a new experimental search for a permanent electric dipole moment of 199Hg utilizing a stack of four vapor cells. We find d(199Hg) = (0.49 \pm 1.29_stat \pm…
Precision measurement of light shifts at two off-resonant wavelengths in a single trapped Ba+ ion and determination of atomic dipole matrix elements
J. A. Sherman, A. Andalkar, W. Nagourney +1
We define and measure the ratio (R) of the vector ac-Stark effect (or light shift) in the 6S_1/2 and 5D_3/2 states of a single trapped barium ion to 0.2% accuracy at two different…
Nuclear magnetic octupole moment and the hyperfine structure of the states of the Ba ion
K. Beloy, A. Derevianko, V. A. Dzuba +3
The hyperfine structure of the long-lived and levels of Ba ion is analyzed. A procedure for extracting relatively unexplored nuclear magnetic moments …
Studies of the S--P transition in atomic ytterbium for optical clocks and qubit arrays
Tao Hong, Claire Cramer, Eryn Cook +2
We report an observation of the weak S-P transition in Yb as an important step to establish Yb as a primary candidate for future optical frequency…
