Ground-state properties of the one-dimensional attractive Hubbard model with confinement: a comparative study
Ji-Hong Hu, Jing-Jing Wang, Gao Xianlong +4
We revisit the one-dimensional attractive Hubbard model by using the Bethe-ansatz based density-functional theory and density-matrix renormalization method. The ground-state proper…

Double occupancies in confined attractive fermions on optical lattices
Ji-Hong Hu, Gao Xianlong
We perform a numerical study of a one-dimensional Fermion-Hubbard model in harmonic traps within the Thomas-Fermi approximation based on the exact Bethe-ansatz solution. The $ρ-U/t…
