Mott Insulator to Superfluid transition in Bose-Bose mixtures in a two-dimensional lattice
M. Guglielmino, V. Penna, B. Capogrosso-Sansone
We perform a numeric study (Worm algorithm Monte Carlo simulations) of ultracold two-component bosons in two-dimensional optical lattices. We study how the Mott insulator to superf…

Quantum signatures of self-trapping transition in attractive lattice bosons
P. Buonsante, V. Penna, A. Vezzani
We consider the Bose-Hubbard model describing attractive bosonic particles hopping across the sites of a translation-invariant lattice, and compare the relevant ground-state proper…
