Competition between spin, charge, and bond waves in a Peierls-Hubbard model.

چکیده
We study a one-dimensional extended Peierls-Hubbard model coupled to intracell and intercell phonons for a half-filled band. The calculations are made using the Hartree-Fock and adiabatic approximations for arbitrary temperature. In addition to static spin, charge, and bond density waves, we predict intermediate phases that lack inversion symmetry, and phase transitions that reduce symmetry on increasing temperature. @S0163-1829~96!04229-4#

Study of the ionic Peierls-Hubbard model using density matrix renormalization group methods
Density matrix renormalization group methods are used to investigate the quantum phase diagram of a one-dimensional half-filled ionic Hubbard model with bond-charge attraction, which can be mapped from the Su-SchriefferHeeger-type electron-phonon coupling at the antiadiabatic limit. A bond order wave (dimerized) phase which separates the band insulator from the Mott insulator always exists as l...
متن کاملStructural Instability in Polyacene: a Projector Quantum Monte Carlo Study
We have studied polyacene within the Hubbard model to explore the effect of electron correlations on the Peierls’ instability in a system marginally away from one-dimension. We employ the projector quantum Monte Carlo method to obtain ground state estimates of the energy and various correlation functions. We find strong similarities between polyacene and polyacetylene which can be rationalized ...
متن کاملA dimerized spin fluid in a one-dimensional electron system
The ground state of a one-dimensional Hubbard model with a bond-charge attraction W term at half-filling is investigated by the density matrix renormalization group method. It is confirmed that the spin gap will be closed at U > 8W . But the long-range bond order wave survives even when the spin gap is closed. It indicates that the ground state is a novel dimerized spin fluid at U > 8W . By a c...
متن کامل2 00 6 Phase diagram of the one dimensional Hubbard - Holstein Model at 1 / 2 and 1 / 4 filling
The Hubbard-Holstein model is one of the simplest to incorporate both electron-electron and electron-phonon interactions. In one dimension at half filling, the Holstein electron-phonon coupling promotes onsite pairs of electrons and a Peierls charge density wave, while the Hubbard onsite Coulomb repulsion U promotes antiferromagnetic correlations and a Mott insulating state. Recent numerical st...
متن کاملModeling electron-electron interactions in reduced-dimensional materials: Bond-charge Coulomb repulsion and dimerization in Peierls-Hubbard models.
To the conventional Peierls-Hubbard model, involving both on-site ( U) and nearest-neighbor ( V) Coulomb repulsions, we add "o5'-diagonal" terms, not expressible purely in terms of site densities, representing bond-bond ( F) and mixed bond-site (X) electron-electron repulsive interactions involving nearest neighbors. We review earlier analyses of these interactions and discuss relative magnitud...
