Optical and DC conductivity of the two-dimensional Hubbard model in the pseudogap regime and across the antiferromagnetic quantum critical point, including vertex corrections
Dominic Bergeron, Vasyl Hankevych, Bumsoo Kyung +1
The conductivity of the two-dimensional Hubbard model is particularly relevant for high-temperature superconductors. Vertex corrections are expected to be important because of stro…
Strong- and weak-coupling mechanisms for pseudogap in electron-doped cuprates
V. Hankevych, B. Kyung, A-M. Dare +2
Using the two-particle self-consistent approach and cluster perturbation theory for the two-dimensional t-t'-t''-U Hubbard model, we discuss weak- and strong-coupling mechanisms fo…
Pseudogap and Spin Fluctuations in the Normal State of Electron-Doped Cuprates
B. Kyung, V. Hankevych, A. -M. Dare +1
We present reliable many-body calculations for the t-t'-t''-U Hubbard model that explain in detail the results of recent angle-resolved photoemission experiments on electron-doped…
Weak ferromagnetism and other instabilities of the two-dimensional t-t' Hubbard model at Van Hove fillings
V. Hankevych, B. Kyung, A. -M. S. Tremblay
We investigate magnetic and superconducting instabilities of the two-dimensional t-t' Hubbard model on a square lattice at Van Hove densities from weak to intermediate coupling by…
Possible Phases of the Two-Dimensional t-t' Hubbard Model
V. Hankevych, F. Wegner
We present a stability analysis of the 2D t-t' Hubbard model on a square lattice for various values of the next-nearest-neighbor hopping t' and electron concentration. Using the fr…
Superconductivity and Instabilities in the t-t' Hubbard Model
F. Wegner, V. Hankevych
We present a stability analysis of the 2D t-t' Hubbard model on a square lattice for t' = -t/6. We find possible phases of the model (d-wave Pomeranchuk and superconducting states,…
