Finite-size effects in transport data from Quantum Monte Carlo simulations
Rubem Mondaini, K. Bouadim, Thereza Paiva +1
We have examined the behavior of the compressibility, the dc-conductivity, the single-particle gap, and the Drude weight as probes of the density-driven metal-insulator transition…
Attractive Hubbard Model on a Honeycomb Lattice
K. L. Lee, K. Bouadim, G. G. Batrouni +4
We study the attractive fermionic Hubbard model on a honeycomb lattice using determinantal quantum Monte Carlo simulations. By increasing the interaction strength U (relative to th…
Magnetic and Transport Properties of a Coupled Hubbard Bilayer with Electron and Hole Doping
K. Bouadim, G. G. Batrouni, F. Hebert +1
The single band, two dimensional Hubbard Hamiltonian has been extensively studied as a model for high temperature superconductivity. While Quantum Monte Carlo simulations within th…
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…
Quantum Monte Carlo Study of an Interaction-Driven Band Insulator to Metal Transition
N. Paris, K. Bouadim, F. Hebert +2
We study the transitions from band insulator to metal to Mott insulator in the ionic Hubbard model on a two dimensional square lattice using determinant Quantum Monte Carlo. Evalua…
