We propose a hardware architecture and protocol for connecting many local quantum
processors contained within an optical cavity. The scheme is compatible with trapped ions or …

We re-evaluate the abundances of the elements in the Sun from copper (Z= 29) to thorium
(Z= 90). Our results are mostly based on neutral and singly-ionised lines in the solar …

Context. We describe the atomic and molecular data that were used for the abundance
analyses of FGK-type stars carried out within the Gaia-ESO Public Spectroscopic Survey in …

We present a method for measuring branching fractions for the decay of J= 1/2 atomic
energy levels to lower-lying states based on time-resolved recording of the atom's …

Motivated by recent measurements for several alkali-metal atoms and alkali-metal-like ions,
we perform a detailed study of electric dipole (E 1) transition amplitudes in K, Ca+, Rb, Sr+ …

Measurement of the Ba+ 138 S 2 1/2-D 2 5/2 clock transition frequency and D 5/2 Landé g J
factor are reported. The clock transition frequency ν Ba+= 170 126 432 449 333.31±(0.39) …

Measurement of the branching ratios for 6 P 1/2 decays to 6 S 1/2 and 5 D 3/2 in Ba+ 138
are reported with the decay probability from 6 P 1/2 to 5 D 3/2 measured to be p …

We present an analysis of the recent measurements of the light-shift ratio in Ba+ at two
different wavelengths that enables us to reduce the uncertainty of the largest E 1 dipole …

Accurate values of electric dipole (E1) amplitudes along with their uncertainties for a number
of transitions among low-lying states of Mg+, Ca+, Sr+, and Ba+ are listed by carrying out …

We present a measurement of the branching fractions for decay from the long-lived 5 D 5/2
level in Ba 138+. The branching fraction for decay into the 6 S 1/2 ground state was found to …
