Electrometry is performed using Rydberg states to evaluate the quadratic Stark shift of the 5s2 1S0-5s5p 3P0 clock transition in strontium. By measuring the Stark shift of the highly excited 5s75d 1D2 state using electromagnetically induced transparency, we characterize the electric field with sufficient precision to provide tight constraints on the systematic shift to the clock transition.

We present a quantitative model for magneto-optical traps operating on narrow transitions, where the transition linewidth and the recoil shift are comparable. We combine a quantum treatment of the light scattering process with a Monte-Carlo simulation of the atomic motion.

We propose and demonstrate the laser cooling and trapping of Rydberg-dressed Sr atoms.

A two-species five-beam magneto-optical trap for highly magnetic Er and Dy atoms

Date: 
2017-11-20
Author(s): 

P. Ilzhöfer, G. Durastante, A. Patscheider, A. Trautmann, M. J. Mark, F. Ferlaino

arXiv:1711.07378

We report on the first realization of a two-species magneto-optical trap (MOT) for erbium and dysprosium. The MOT operates on an intercombination line for the respective species. Owing to the narrow-line character of such a cooling transition and the action of gravity, we demonstrate a novel trap geometry employing only five beams in orthogonal configuration. We observe that the mixture is cooled and trapped very efficiently, with up to 5*108 Er atoms and 1*109 Dy atoms at temperatures of about 10 uK.
