Ground-state instabilities in the one-dimensional Penson-Kolb-Hubbard model.
Different kinds of instabilities (CDW , SDW , SS) in the 1D Hubbard model with pair-hopping interaction are investigated using an approximate Bethe-Salpeter equation. The study is performed at any density of electrons and for arbitrary values of the model parameters. In the absence of the on-site interaction, no transition occurs at half filling for any finite negative pair-hopping parameter, i...
متن کاملComment on "Ground-state phase diagram of a half-filled one-dimensional extended Hubbard model".
The density-matrix renormalization group is used to study the phase diagram of the one-dimensional half-filled Hubbard model with on-site (U) and nearest-neighbor (V) repulsion and hopping t. A critical line V(c)(U) approximately U/2 separates a Mott insulating phase from a charge-density-wave phase. The formation of bound charge excitations for V>2t changes the phase transition from continuous...
متن کاملIncremental expansions for the ground state energy of the two-dimensional Hubbard model
A generalization of Faddeev’s approach of the 3-body problem to the manybody problem leads to the method of increments. This method was recently applied to account for the ground state properties of Hubbard-Peierls chains (JETP Letters 67 (1998) 1052). Here we generalize this approach to twodimensional square lattices and explicitely treat the incremental expansion up to third order. Comparing ...
متن کاملFerromagnetic Domain Wall and Spiral Ground States in One-Dimensional Deformed Flat-Band Hubbard Model
We construct a set of exact ground states with a localized ferromagnetic domain wall and an extended spiral structure in a quasi-one-dimensional deformed flatband Hubbard model. In the case of quarter filling, we show the uniqueness of the ground state with a fixed magnetization. The ground states with these structures are degenerate with the all-spin-up and all-spin-down states. This property ...
متن کاملGround state and excitations of the extended Hubbard model
We examine the ground state and excitations of the one dimensional extended Hubbard model with long range interaction. The ground state wavefunction and low lying excitations are given explicitly in the form of a Jastrow product of two-body terms. This result motivates an asymptotic Bethe ansatz solution for the model. We present evidence that this solution is in fact exact and spans the comple...
