17. The case of atomic species with different masses can also be exactly solved within the Gaudin algebra. Since this is of experimental relevance we write down the Hamiltonian, H= iL εi [NiG + NiB + (1+Δ) NiR] -g i i′ L α A iα † A i′ α -2g i i′ L α β Ciαβ C i′ βα, where Δ quantifies the difference in the atomic masses.
18. A quantum phase diagram is usually defined in the thermodynamic limit. In that limit the transition to a superfluid state at P=0 takes place at g=0 and, therefore, it is expected that the boundary between the normal and the superfluid phases will move to the left defining the Chandrasekhar-Clogston limit of a three-color Fermi gas.
