Independent Control of Scattering Lengths in Multicomponent Quantum Gases

Abstract

We develop a method of simultaneous and independent control of different scattering lengths in ultracold multicomponent atomic gases, such as $ \mathrm{40}}$K or $^{\mathrm{40}} $K-$^{\mathrm{6}}$Li mixture. Our method can be used to engineer multi-component quantum phases and Efimov trimer states.
