Bosonic Kondo-Hubbard model
T. Flottat, F. Hébert, V. G. Rousseau +2
We study, using quantum Monte-Carlo simulations, the bosonic Kondo-Hubbard model in a two dimensional square lattice. We explore the phase diagram and analyse the mobility of parti…
Competing Supersolid and Haldane Insulator phases in the extended one-dimensional bosonic Hubbard model
G. G. Batrouni, R. T. Scalettar, V. G. Rousseau +1
The Haldane Insulator is a gapped phase characterized by an exotic non-local order parameter. The parameter regimes at which it might exist, and how it competes with alternate type…
Finite temperature QMC study of the one-dimensional polarized Fermi gas
M. J. Wolak, V. G. Rousseau, C. Miniatura +3
Quantum Monte Carlo (QMC) techniques are used to provide an approximation-free investigation of the phases of the one-dimensional attractive Hubbard Hamiltonian in the presence of…
Pure Mott phases in confined ultracold atomic systems
V. G. Rousseau, G. G. Batrouni, D. E. Sheehy +2
We propose a novel scheme for confining atoms to optical lattices by engineering a spatially-inhomogeneous hopping matrix element in the Hubbard-model (HM) description, a situation…
Quantum Monte Carlo study of the visibility of one-dimensional Bose-Fermi mixtures
C. N. Varney, V. G. Rousseau, R. T. Scalettar
The study of ultracold optically trapped atoms has opened new vistas in the physics of correlated quantum systems. Much attention has now turned to mixtures of bosonic and fermioni…
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…
Collective Oscillations of Strongly Correlated One-Dimensional Bosons on a Lattice
M. Rigol, V. Rousseau, R. T. Scalettar +1
We study the dipole oscillations of strongly correlated 1D bosons, in the hard-core limit, on a lattice, by an exact numerical approach. We show that far from the regime where a Mo…
Spin and charge dynamics of stripes in doped Mott insulators
F. F. Assaad, V. Rousseau, F. Hebert +2
We study spin and charge dynamics of stripes in doped Mott insulators by considering a two-dimensional Hubbard model with N fermion flavors. For N =2 we recover the normal one-band…
