Metallicity in the half-filled Holstein-Hubbard model
We re-examine the Peierls insulator to Mott insulator transition scenario in the one-dimensional Holstein-Hubbard model where, at half-filling, electron-phonon and electron-electron interactions compete for establishing chargeand spin-density-wave states, respectively. By means of large-scale density-matrix renormalization group calculations we determine the spin, single-particle and two-partic...
متن کاملHalf-filled stripes in the t-t-U Hubbard model
Using a self-consistent Hartree-Fock approximation we investigate the relative stability of various stripe phases in the extended t-t-U Hubbard model. One finds that a negative ratio of nextto nearest-neighbor hopping t/t < 0 expells holes from antiferromagnetic domains and reinforces the stripe order. Therefore the half-filled stripes not only accommodate holes but also redistribute them so th...
متن کاملQuantum-disentangled liquid in the half-filled Hubbard model
We investigate the existence of quantum disentangled liquid (QDL) states in the half-filled Hubbard model on bipartite lattices. In the one dimensional case we employ a combination of integrability and strong coupling expansion methods to argue that there are indeed finite energy-density eigenstates that exhibit QDL behaviour in the sense of J. Stat. Mech. P10010 (2014). The states exhibiting t...
متن کاملCompetition between antiferromagnetic and charge-density-wave order in the half-filled Hubbard-Holstein model.
We present a determinant quantum Monte Carlo study of the competition between instantaneous on-site Coulomb repulsion and retarded phonon-mediated attraction between electrons, as described by the two-dimensional Hubbard-Holstein model. At half filling, we find a strong competition between antiferromagnetism (AFM) and charge-density-wave (CDW) order. We demonstrate that a simple picture of AFM-...
متن کاملDimerization in a half-filled one-dimensional extended hubbard model.
We use a density-matrix renormalization group method to study quantitatively the phase diagram of a one-dimensional extended Hubbard model at half filling by investigating the correlation functions and structure factors. We confirmed the existence of a novel narrow region with long-range bond-order-wave order that was highly controversial recently between the charge-density-wave phase and Mott ...
