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…
Layering and superfluidity of soft-core bosons in shallow spherical traps
Fabio Cinti, Matteo Ciardi, Santi Prestipino +1
Fundamental theories and models of many-body physics can be probed in experiments on ultracold atoms held in place by electromagnetic fields. In particular, of considerable interes…
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…
Effects of gravity on supersolid order in bubble-trapped bosons
Matteo Ciardi, Fabio Cinti, Giuseppe Pellicane +1
Unveiling the principles behind self-organization in quantum systems is of paramount importance, both intrinsically and practically, in view of foreseeable technological applicatio…
