Hole Binding around Ni Impurity in Cuprates
K. Tsutsui, A. Toyama, T. Tohyama +1
We examine the influence of Ni impurity in cuprates on the distribution of hole carriers by performing numerically exact diagonalization calculations for a model consisting of Cu3d…
Bipolaron in the t-J model coupled to longitudinal and transverse quantum lattice vibrations
Lev Vidmar, Janez Bonca, Sadamichi Maekawa +1
We explore the influence of two different polarizations of quantum oxygen vibrations on the spacial symmetry of the bound magnetic bipolaron in the context of the t-J model by usin…
Effect of Fermi Surface Topology on Inter-Layer Magnetoresistance in Layered Multiband Systems: Application to LaFeAsO1-xFx
Takao Morinari, Hiroki Nakamura, Masahiko Machida +1
In layered single band systems, the interlayer conductivity depends on the orientation of the in-plane magnetic field and takes maximum values when the magnetic field is perpendicu…
Induced Order in Nonequivalent Two-Leg Hubbard Ladder
Hiroyuki Yoshizumi, Takami Tohyama, Takao Morinari
Motivated by the presence of different orders in multilayered high-temperature superconductors, we examine a model consisting of nonequivalent two Hubbard chains coupled by interch…
