12. The Bose-Bose mixture considered by T. Roscilde and J.I. Cirac, Phys. Rev. Lett. PRLTAO 0031-9007 98, 190402 (2007) exhibits many metastable states, characterized by microscopic phase separation. Note that such mixtures in certain limits can be described by an effective extended Hubbard model for composite bosons. 10.1103/PhysRevLett.98.190402
