Species-Selective Manipulation of a Multi-Component Quantum Gas
We have realised a scheme in which species-selective control is achieved using magnetic potentials dressed with multiple radiofrequencies (RFs), exploiting the different Lande gF -factors of the constituent atomic species [1,2,3]. The resulting potentials have low heating rates, and are extremely smooth and free from defects. Species with Lande g-factors that differ in sign or magnitude can be manipulated independently. We use a mixture of either two distinct atoms (Rb-87 and Rb-85) or different hyperfine states of the same atom (Rb-87, F = 1 & F = 2).
