Quantum Monte Carlo Study of a Dynamic Hubbard Model
K. Bouadim, M. Enjalran, F. Hebert +2
The `dynamic' Hubbard Hamiltonian describes interacting fermions on a lattice whose on-site repulsion is modulated by a coupling to a fluctuating bosonic field. We investigate one…
Mott insulators and correlated superfluids in ultracold Bose-Fermi mixtures
F. Hebert, F. Haudin, L. Pollet +1
We study the effects of interaction between bosons and fermions in a Bose-Fermi mixtures loaded in an optical lattice. We concentrate on the destruction of a bosonic Mott phase dri…
Metallic phase in the two-dimensional ionic Hubbard model
K. Bouadim, N. Paris, F. Hebert +2
We investigate the phases of the ionic Hubbard model in a two-dimensional square lattice using determinant quantum Monte Carlo (DQMC). At half-filling, when the interaction strengt…
Supersolid phases in the one dimensional extended soft core Bosonic Hubbard model
G. G. Batrouni, F. Hebert, R. T. Scalettar
We present results of Quantum Monte Carlo simulations for the soft core extended bosonic Hubbard model in one dimension exhibiting the presence of supersolid phases similar to thos…
