Spatial Structure of Spin Polarons in the t-J Model
A. Ramsak, P. Horsch
The deformation of the quantum Neel state induced by a spin polaron is analyzed in a slave fermion approach. Our method is based on the selfconsistent Born approximation for Green'…
The GW method
F. Aryasetiawan, O. Gunnarsson
Calculations of ground-state and excited-state properties of materials have been one of the major goals of condensed matter physics. Ground-state properties of solids have been ext…
Buckling and d-Wave Pairing in HiTc-Superconductors
O. Jepsen, O. K. Andersen, I. Dasgupta +1
We have investigated whether the electron-phonon interaction can support a d-wave gap-anisotropy. On the basis of models derived from LDA calculations, as well as LDA linear-respon…
Normal and superconducting state in the presence of forward electron-phonon and impurity scattering
O. V. Danylenko, O. V. Dolgov, M. L. Kulic +1
Impurities with the pronounced forward scattering (FS impurities) change analytical properties of the quasiparticle Green's function substantially compared to the isotropic scatter…
Effects of nonstoichiometry in A3C60 (A= K, Rb)
O. Gunnarsson
We perform self-consistent Hartree calculations for a model of A_{3-x}C_{60} (A= K, Rb) to study the effects of the presence of vacancies. We find that the strong vacancy potential…
Spin and orbital excitation spectrum in the Kugel-Khomskii model
G. Khaliullin, V. Oudovenko
We discuss spin and orbital ordering in the twofold orbital degenerate superexchange model in three dimensions relevant to perovskite transition metal oxides. We focus on the parti…
