Half-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 کاملIncipient antiferromagnetism and low-energy excitations in the half-filled two-dimensional Hubbard model.
We present single-particle and thermodynamic properties of the half-filled single-band Hubbard model in 2D calculated in the self-consistent fluctuation exchange approximation. The low-energy excitations at moderate temperatures and small U are quasiparticles with a short lifetime. As the temperature is lowered, coupling to evolving spin fluctuations leads to the extinction of these quasipartic...
متن کاملSuperconducting phase and pairing fluctuations in the half-filled two-dimensional Hubbard model.
The two-dimensional Hubbard model exhibits superconductivity with d-wave symmetry even at half-filling in the presence of a next-nearest neighbor hopping. Using plaquette cluster dynamical mean-field theory with a continuous-time quantum Monte Carlo impurity solver, we reveal the non-Fermi liquid character of the metallic phase in proximity to the superconducting state. Specifically, the low-fr...
متن کاملSpin fluctuations and pseudogap in the two-dimensional half-filled Hubbard model at weak coupling
– Starting from the Hubbard model in the weak-coupling limit, we derive a spinfermion model where the collective spin excitations are described by a non-linear sigma model. This result is used to compute the fermion spectral function A(k, ω) in the low-temperature regime where the antiferromagnetic (AF) coherence length is exponentially large (“renormalized classical” regime). At the Fermi leve...
متن کاملSlow dynamics in a two-dimensional Anderson- Hubbard model
We study the real-time dynamics of a two-dimensional Anderson-Hubbard model using nonequilibrium self-consistent perturbation theory within the second-Born approximation. When compared with exact diagonalization performed on small clusters, we demonstrate that for strong disorder this technique approaches the exact result on all available timescales, while for intermediate disorder, in the vici...
