Two electrons are better than one... In the Yb lab we produce Bose-Einstein condensates and degenerate Fermi gases of ytterbium atoms. These atoms offer metastable electronic states, ultranarrow clock transitions, multicomponent fermions with SU(N) interactions: a whole range of experimental tools that allow new possibilities for quantum simulation and quantum information processing.

Probing state-dependent interactions in bosonic Ytterbium

We report on the measurement of the scattering properties of ultracold 174Yb bosons in a three-dimensional optical lattice. Site occupancy in an atomic Mott insulator is resolved with high-precision spectroscopy on an ultranarrow, metrological optical clock transition. Scattering lengths and loss rate coefficients for 174Yb atoms in different collisional channels involving the ground state 1S0 and the metastable 3P0 states are derived. These studies set important constraints for future experimental studies of two-electron atoms for quantum-technological applications
