The pseudogap in high- superconductors from SU(2) gauge symmetry and dynamic correlation effects
I. A. Goremykin, A. A. Katanin
We consider the spectral properties of the two-dimensional Hubbard model, describing the electronic properties of high- compounds, within the SU(2) gauge theory, which assumes…
Frequency dependence of temporal spin stiffness and short-range magnetic order in the doped two-dimensional Hubbard model
I. A. Goremykin, A. A. Katanin
We study doping and temperature dependencies of temporal and spatial spin stiffnesses of the Hubbard model within the mean field approach for incommensurate magnetic order. We show…
Antiferromagnetic and spin spiral correlations in the doped two-dimensional Hubbard model: gauge symmetry, Ward identities, and dynamical mean-field theory analysis
I. A. Goremykin, A. A. Katanin
We reconsider the derivation of Ward identities for spin stiffnesses, which determine the non-linear sigma model of magnetic degrees of freedom of interacting electrons in the pres…
Commensurate and incommensurate magnetic order in the doped two-dimensional Hubbard model: dynamical mean-field theory analysis
I. A. Goremykin, A. A. Katanin
We develop a dynamical mean-field theory approach for the spiral magnetic order, changing to a local coordinate frame with preferable spin alignment along the -axis, which can b…
