Accurate prediction of clock transitions in a highly charged ion with complex electronic structure
C. Cheung, M. S. Safronova, S. G. Porsev +3
We have developed a broadly-applicable approach that drastically increases the ability to accurately predict properties of complex atoms. We applied it to the case of Ir, w…
Feshbach resonances in -wave three-body recombination within Fermi-Fermi mixtures of open-shell Li and closed-shell Yb atoms
Alaina Green, Hui Li, Jun Hui See Toh +6
We report on observations and modeling of interspecies magnetic Feshbach resonances in dilute ultracold mixtures of open-shell alkali-metal Li and closed-shell Yb atoms…
State-dependent optical lattices for the strontium optical qubit
A. Heinz, A. J. Park, N. Šantić +5
We demonstrate state-dependent optical lattices for the Sr optical qubit at the tune-out wavelength for its ground state. We tightly trap excited state atoms while suppressing the…
High Resolution Photoexcitation Measurements Exacerbate the Long-Standing Fe XVII Oscillator Strength Problem
Steffen Kühn, Chintan Shah, José R. Crespo López-Urrutia +29
For more than 40 years, most astrophysical observations and laboratory studies of two key soft x-ray diagnostic transitions, and , in Fe XVII ions found oscillator…
High-precision measurement and ab initio calculation of the electric quadrupole transition amplitude in Pb
Daniel L. Maser, Eli Hoenig, B. -Y. Wang +4
We have completed a measurement of the 939 nm electric quadrupole () transition amplitude in atomic lead. Using a Faraday rotation…
Combining experiments and relativistic theory for establishing accurate radiative quantities in atoms: the lifetime of the P state in Ca
Ziv Meir, Mudit Sinhal, Marianna S. Safronova +1
We report a precise determination of the lifetime of the (4p)P state of Ca, ns, using a combination of measurements of the i…
Wilson loop and Wilczek-Zee phase from a non-Abelian gauge field
Seiji Sugawa, Francisco Salces-Carcoba, Yuchen Yue +2
Quantum states can acquire a geometric phase called the Berry phase after adiabatically traversing a closed loop, which depends on the path not the rate of motion. The Berry phase…
Magic wavelength of the Ba clock transition

The zero crossing of the dynamic differential scalar polarizability of the clock transition in Ba has been determined to be THz. Toget…
Narrow-line Cooling and Determination of Magic Wavelength of Cd
A. Yamaguchi, M. S. Safronova, K. Gibble +1
We experimentally and theoretically determine the magic wavelength of the (5)(55) clock transition of Cd to be 419.88(14) nm and 420.1(7…
