This study demonstrates the existence of a new superfluid state in a three-component Bose mixture trapped in an optical lattice, where superfluid transport involving all three components is hindered and dissipationless counterflows between any pair of components are allowed. The presence of three components allows for three different types of counterflows with only two independent superfluid degrees of freedom.
We demonstrate microscopically the existence of a new superfluid state of matter in a three-component Bose mixture trapped in an optical lattice. The superfluid transport involving coflow of all three components is arrested in that state, while counterflows between any pair of components are dissipationless. The presence of three components allows for three different types of counterflows with only two independent superfluid degrees of freedom.
