Bose-Bose mixtures in an optical lattice: First-order superfluid-insulator transition and elementary excitations
Takeshi Ozaki, Ippei Danshita, Tetsuro Nikuni
We study ground-state phase diagrams and excitation spectra of Bose-Bose mixtures in an optical lattice by applying the Gutzwiller approximation to the two-component Bose-Hubbard m…

Phase Separation in Bose-Bose Mixtures in an Optical Lattice
Takeshi Ozaki, Tetsuro Nikuni
We study the ground-state properties of mixtures of strongly interacting bosonic atoms in an optical lattice. Applying a mean-field approximation to the Hubbard model for Bose-Bose…
