We study a system of electrons interacting through long-range Coulomb forces on a one-dimensional lattice, by means of a variational ansatz which is the strong-coupling counterpart of the Gutzwiller wave function. Our aim is to describe the quantum analogue of Hubbard's classical ``generalized Wigner crystal.'' We first analyze charge ordering in a system of spinless fermions, with particular attention to the effects of lattice commensurability. We argue that for a general (rational) number of… 
Wigner Crystallization of Electrons in a One-Dimensional Lattice: A Condensation in the Space of States.
TLDR
The ground state of a system of spinless electrons interacting through a screened Coulomb potential in a lattice ring is studied and it is shown that, when the effective interaction compares with the kinetic energy, the system forms a Wigner crystal undergoing a first-order quantum phase transition.
One-dimensional narrow-band conductors
We review one-dimensional lattice models and the corresponding results that describe the low-temperature properties of quasi-one-dimensional lattice systems with long-range interaction. A widely
Exact diagonalization of a one-dimensional Hubbard model at density rho=0.4: Effects of Coulomb repulsions and distant transfer
An extended Hubbard model that includes not only on-site but also intersite Coulomb repulsion and distant transfer is numerically investigated using the exact Lanczos diagonalization method for
Variational study of the interacting, spinless Su-Schrieffer-Heeger model.
TLDR
To obtain the ground state wave-function, the Baeriswyl variational wave function is extended to account for alternating hopping parameters and results suggest that the correlation acts to break the chiral symmetry of the Su-Schrieffer-Heeger model, in the same way as it happens when a Rice-Mele onsite potential is turned on.
Density functional study of collective electron localization: detection by persistent current.
TLDR
The calculation shows that the macroscopic current, which is a quantity directly accessible in DFT, can serve as an indicator of the formation of a correlated electron state, as expected in the mean-field-type DFT-OEP approach.
Second-order electronic correlation effects in a one-dimensional metal
The Pariser-Parr-Pople (PPP) model of a single-band one-dimensional (1D) metal is studied at the Hartree-Fock level, and by using the second-order perturbation theory of the electronic correlation.
Strong Coulomb effects in hole-doped Heisenberg chains
Abstract.Substances such as the “telephone number compound” Sr14Cu24O41 are intrinsically hole-doped. The involved interplay of spin and charge dynamics is a challenge for theory. In this article

TLDR
The results allow a consistent interpretation of the plasmon and spin excitations observed in one-dimensional semiconductor structures, and suggest an interpretation of some of the observed features in terms of ``spinons.
Quantum phase transitions to charge-ordered and Wigner-crystal states under the interplay of lattice commensurability and long-range Coulomb interactions.
TLDR
The relationship among the Wigner crystal, charge ordering, and the Mott insulator is studied by the path-integral renormalization group method in two-dimensional systems with long-range Coulomb interaction, showing a large reduction from r(s) approximately 35 in the continuum limit.

TLDR
The critical behavior shows that the Mott transition is infinite order for all t', whether or not a spin gap is present, and that hyperscaling holds.

TLDR
The electron system is found to be in the normal- (paramagnetic) fluid state below the transition density, but the fully polarized state is very close in energy.
