Feshbach-Einstein condensates
Valy G. Rousseau, Peter J. H. Denteneer
We investigate the phase diagram of a two-species Bose-Hubbard model describing atoms and molecules on a lattice, interacting via a Feshbach resonance. We identify a region where t…
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…
Determinant Quantum Monte Carlo Study of the Screening of the One Body Potential near a Metal-Insulator Transition
P. B. Chakraborty, P. J. H. Denteneer, R. T. Scalettar
In this paper we present a determinant quantum monte carlo study of the two dimensional Hubbard model with random site disorder. We show that, as in the case of bond disorder, the…
Phase coherence, visibility, and the superfluid--Mott-insulator transition on one-dimensional optical lattices
P. Sengupta, M. Rigol, G. G. Batrouni +2
We study the phase coherence and visibility of trapped atomic condensates on one-dimensional optical lattices, by means of quantum Monte-Carlo simulations. We obtain structures in…
Dynamic response of trapped ultracold bosons on optical lattices
G. G. Batrouni, F. F. Assaad, R. T. Scalettar +1
We study the dynamic response of ultracold bosons trapped in one-dimensional optical lattices using Quantum Monte Carlo simulations of the boson Hubbard model with a confining pote…
Critical temperature for the two-dimensional attractive Hubbard Model
Thereza Paiva, Raimundo R. dos Santos, R. T. Scalettar +1
The critical temperature for the attractive Hubbard model on a square lattice is determined from the analysis of two independent quantities, the helicity modulus, , and the pa…
