Abstract

Bosonic ⁵²Cr, which lias recently been cooled down to quantum degeneracy [1], has as main specificity its large magnetic dipole moment of 6p_B in the ground state. Chromium stands as a good candidate for studying new physics in the degenerate regime, with important long range, anisotropic, dipole-dipole interactions. Cr has a relatively abundant (9%) fermionic isotope (⁵³Cr). We demonstrated the possibility of magnetically trapping ⁵³Cr atoms, as well as both Cr isotopes simultaneously [2], This opens new perspectives for our experiment towards producing ultracold Fenni-Bose degenerate dipolar mixtures.
