“…The spectra at T = 100 µK and 1 mK clearly show the influence of the d-wave reso- nance. This resonance had a crucial role in the correct interpretation of photoassociation spectra near the resonance transition 1 S 0 − 3 P 1 and in the determination of the scattering length for this isotope [58]. When the spectrum is dominated by the features due to the ground state d-wave, the intensity ratio of the J e = 3 and J e = 1 features should be 3/2 from Eq.…”

The properties of bosonic Ytterbium photoassociation spectra near the intercombination transition 1 S0-3 P1 are studied theoretically at ultra low temperatures. We demonstrate how the shapes and intensities of rotational components of optical Feshbach resonances are affected by mass tuning of the scattering properties of the two colliding ground state atoms. Particular attention is given to the relationship between the magnitude of the scattering length and the occurrence of shape resonances in higher partial waves of the van der Waals system. We develop a mass scaled model of the excited state potential that represents the experimental data for different isotopes. The shape of the rotational photoassociation spectrum for various bosonic Yb isotopes can be qualitatively different.

“…In this model the line-strength and excitation energy for the resonant excitation energy are set to experimental values. The line strength, 17.25 (7), was taken as the average of the two photoassociation line strengths [56,57] and its uncertainty was dervied from the difference of the two values and the quoted uncertainty of Ref. [57].…”

Tune-out wavelengths for the alkaline-earth-metal atoms

The lowest 3 tune-out wavelengths of the four alkaline-earth atoms, Be, Mg, Ca and Sr are determined from tabulations of matrix elements produced from large first principles calculations. The tune-out wavelengths are located near the wavelengths for 3 P o 1 and 1 P o 1 excitations. The measurement of the tune-out wavelengths could be used to establish a quantitative relationship between the oscillator strength of the transition leading to existence of the tune-out wavelength and the dynamic polarizability of the atom at the tune-out frequency. The longest tune-out wavelengths for Be, Mg, Ca, Sr, Ba and Yb are 454.9813 nm, 457.2372 nm, 657.446 nm, 689.200 nm, 788.875 nm and 553.00 nm respectively.

We carry out relativistic many-body calculations of the static and dynamic dipole polarizabilities of the ground 6s 2 1 S0 and the first excited 6s6p 3 P o 0 states of Yb. With these polarizabilities, we compute several properties of Yb relevant to optical lattice clocks operating on the 6stransition. We determine (i) the first four magic wavelengths of the laser field for which the frequency of the clock transition is insensitive to the laser intensity. While the first magic wavelength is known, we predict the second, the third and the forth magic wavelengths to be 551 nm, 465 nm, and 413 nm.(ii) We reevaluate the effect of black-body radiation on the frequency of the clock transition, the resulting clock shift at T = 300 K being −1.41(17) Hz. (iii) We compute long-range interatomic van der Waals coefficients (in a.u.) C6(6s S0) = 3.34 and C3(6s6p 3 P0) = 3.68. We also address and resolve a disagreement between previous calculations of the static polarizability of the ground state.
