Extended Bose-Hubbard Model on Small Grids: Exact Diagonalization and Monte Carlo Studies
Gabriele Costa, Matteo Ciardi, Fabio Cinti +1
The superfluid-insulator transition in systems of lattice bosons is usually analyzed in the framework of the Bose-Hubbard model, and has been extensively studied by theory and simu…

Onset of stripe order in classical fluids: Lessons from lattice-gas mixtures
Gabriele Costa, Santi Prestipino
When two molecular species with mutual affinity are mixed together, various self-assembled phases can arise at low temperature, depending on the shape of like and unlike interactio…

Wang-Landau study of lattice gases on geodesic grids
Gabriele Costa, Santi Prestipino
We study a family of lattice-gas systems defined on semiregular grids, obtained by projecting the vertices of three different geodesic icosahedra onto a spherical surface. By using…
