Abstract

A new one-dimensional model of strongly correlated fermions on N sublattices with density-density interaction and pair hopping between sublattices is formulated and solved exactly by the Bethe ansatz method. The density-density and pair correlation functions are calculated which manifest superconducting properties for N ⩾ 3.

A New Integrable Two-Parameter Model of Strongly Correlated Electrons in One Dimension

R. Z Bariev, A Klümper, J Zittartz

A new one-dimensional fermion model depending on two independent interaction parameters is formulated and solved exactly by the Bethe-ansatz method. The Hamiltonian of the model contains the Hubbard interaction and correlated hopping as well as pair hopping terms. The density-density and pair correlations are calculated which manifest superconducting properties in certain regimes of the phase diagram.

A one-dimensional integrable model of fermions with multi-particle hopping

R. Z. Bariev, Andreas Klümper, Andreas Schadschneider +1 more

A model with both single-particle and multi-particle hopping of electrons on a one-dimensional 'triangular' lattice is formulated and solved exactly by Bethe ansatz. On the basis of the exact calculation of the asymptotic behaviour of correlation functions we find a transition between the normal state and a state with a tendency to 'superconductivity'. The latter state is confined to small densities of electrons up to a critical density rho c .

Model of Fermions with Correlated Hopping (Integrable Cases)

Igor N. Karnaukhov

We present a new model describing strongly correlated electrons on a lattice. The model naturally describes the nearest-neighbor hopping of electrons and local electron pairs and the interaction between them. It is an extended Hubbard model exactly solvable in one dimension for some special values of the coupling constants. The Bethe ansatz equation are obtained and a ground state is discussed.

Exact solution of a one-dimensional fermion model with interchain tunneling

R. Z. Bariev, Andreas Klümper, Andreas Schadschneider +1 more

A fermion model consisting of two chains with interchain tunneling is formulated and solved exactly by the Bethe-ansatz method. The interchain tunneling leads to Cooper-pair-like bound states and a threshold energy is required to overcome the binding energy. The correlation functions manifest superconducting properties.

New Exactly Solvable One-Parameter Model of Strongly Correlated Electrons

Igor N. Karnaukhov

We present a two band fermion model consisting of a subband of conduction electrons and a subband of local electron pairs interacting via interband interactions. The model is solved in one dimension by means of the Bethe ansatz for an empty subband of local electron pairs. The ground state energy, the chemical potential, the critical exponents, describing the asymptotic behavior of correlation functions at long distances, the effective electron transport mass have been calculated numerically for an arbitrary density of conduction electrons.

Integrable fermion model with hopping integrals for many-particle configurations

Igor N. Karnaukhov

One parametric one-dimensional spinless fermion model is formulated and solved exactly by the Bethe ansatz method. The Hamiltonian contains the kinetic terms describing nearest-neighbor hopping of electrons with different hopping integrals for many-particle configurations. The Luttinger liquid behavior is studied for the case repulsion effective interaction. The ground-state energy, the critical exponent, describing the asymptotic behavior of the density-density correlation function at long distances, the Fermi velocity have been calculated numerically for an arbitrary density of electrons. The model displays the condensation of particles in the case of the attractive interaction.
