We report on the attainment of Bose-Einstein condensation with ultracold strontium atoms. We use the 84Sr isotope, which has a low natural abundance but offers excellent scattering properties for evaporative cooling. Accumulation in a metastable state using a magnetic-trap, narrowline cooling, and straightforward evaporative cooling in an optical trap lead to pure condensates containing 1.5×105 atoms. This puts 84Sr in a prime position for experiments on quantum-degenerate gases involving atomic two-electron systems.
Furthermore, we report on recent advances towards a degenerate Fermi gas of 87Sr. Ideas of future experiments related to quantum simulation and ultracold SrRb molecules will also be discussed in the talk.
