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…

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…
