Magnetic Moment Collapse-Driven Mott Transition in MnO
Jan Kunes, Alexey V. Lukoyanov, Vladimir I. Anisimov +2
The metal-insulator transition in correlated electron systems, where electron states transform from itinerant to localized, has been one of the central themes of condensed matter p…
Superfluid and Mott Insulator phases of one-dimensional Bose-Fermi mixtures
A. Zujev, A. Baldwin, R. T. Scalettar +3
We study the ground state phases of Bose-Fermi mixtures in one-dimensional optical lattices with quantum Monte Carlo simulations using the Canonical Worm algorithm. Depending on 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…
Exact Numerical Study of Pair Formation with Imbalanced Fermion Populations
G. G. Batrouni, M. H. Huntley, V. G. Rousseau +1
We present an exact Quantum Monte Carlo study of the attractive 1-dimensional Hubbard model with imbalanced fermion population. The pair-pair correlation function, which decays mon…
s-wave Superconductivity Phase Diagram in the Inhomogeneous Two-Dimensional Attractive Hubbard Model
K. Aryanpour, T. Paiva, W. E. Pickett +1
We study s-wave superconductivity in the two-dimensional square lattice attractive Hubbard Hamiltonian for various inhomogeneous patterns of interacting sites. Using the Bogoliubov…
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…
