title: 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 atomic gases, such as ;{40}K or a ;{40}K-;{6}Li mixture. Our method can be used to engineer multicomponent quantum phases and Efimov trimer states.
