Unconventional quantum phases of lattice bosonic mixtures
P. Buonsante, S. M. Giampaolo, F. Illuminati +2
We consider strongly interacting boson-boson mixtures on one-dimensional lattices and, by adopting a qualitative mean-field approach, investigate their quantum phases as the inters…
Theory of ground state factorization in quantum cooperative systems
S. M. Giampaolo, G. Adesso, F. Illuminati
We introduce a general analytic approach to the study of factorization points and factorized ground states in quantum cooperative systems. The method allows to determine rigorously…
Mixtures of strongly interacting bosons in optical lattices
P. Buonsante, S. M. Giampaolo, F. Illuminati +2
We investigate the properties of strongly interacting heteronuclear boson-boson mixtures loaded in realistic optical lattices, with particular emphasis on the physics of interfaces…
Extended Bose Hubbard model of interacting bosonic atoms in optical lattices: from superfluidity to density waves
G. Mazzarella, S. M. Giampaolo, F. Illuminati
For systems of interacting, ultracold spin-zero neutral bosonic atoms, harmonically trapped and subject to an optical lattice potential, we derive an Extended Bose Hubbard (EBH) mo…
Influence of trapping potentials on the phase diagram of bosonic atoms in optical lattices
S. M. Giampaolo, F. Illuminati, G. Mazzarella +1
We study the effect of external trapping potentials on the phase diagram of bosonic atoms in optical lattices. We introduce a generalized Bose-Hubbard Hamiltonian that includes the…
