Topological phases of the Kitaev-Hubbard model at half filling
The Kitaev-Hubbard model of interacting fermions is defined on the honeycomb lattice and, at strong coupling, interpolates between the Heisenberg model and the Kitaev model. It is basically a Hubbard model with ordinary hopping t and spin-dependent hopping t ′. We study this model in the weak to intermediate coupling regime, at half filling, using the cellular dynamical impurity approximation (...
متن کاملAntiferromagnetism of the 2D Hubbard Model at Half Filling: Analytic Ground State at Weak Coupling
r n̂r↑n̂r↓. In Shf we study the many-body eigenstates of the kinetic energy with vanishing eigenvalue of the Hubbard repulsion (W = 0 states). In the Sz = 0 sector, this is a N times degenerate multiplet. From the singlet component one obtains the ground state of the Hubbard model for U = 0, which is unique in agreement with a theorem by Lieb. The wave function demonstrates an antiferromagnetic o...
متن کاملOn the Scaling Limit of the 1D Hubbard Model at Half Filling
The dispersion relations and S-matrix of the one-dimensional Hubbard model at half filling are considered in a certain scaling limit. (In the process we derive a useful smallcoupling expansion of the exact lattice dispersion relations.) The resulting scattering theory is consistently identified as that of the SU(2) chiral-invariant Thirring (or GrossNeveu) field theory, containing both massive ...
متن کاملVariational cluster approximation study of the one-dimensional Holstein-Hubbard model at half filling
The half-filled one-dimensional Holstein-Hubbard model presents, at zero temperature, a charge-density-wave (CDW) phase and a Mott insulator phase. Recent results have shown that the transition from one phase to the other might proceed through an intermediate metallic phase. In this work, we determine the CDW phase boundary using the variational cluster approximation. Using exact diagonalizatio...
متن کاملProperties of the U À t One-Dimensional Hubbard Model at Half-Filling
We examine the one-dimensional Hubbard model and derive expressions for the chemical potential and momentum distribution in the limit of strong electron-electron interactions to first order in perturbation theory. By showing that the perturbation matrix is stochastic, the chemical potential is found to depend only on the model parameters and not on the system size, consistent with the well-know...
