The 3-Band Hubbard-Model versus the 1-Band Model for the high-Tc Cuprates: Pairing Dynamics, Superconductivity and the Ground-State Phase Diagram
W. Hanke, M. L. Kiesel, M. Aichhorn +2
One central challenge in high- superconductivity (SC) is to derive a detailed understanding for the specific role of the - and - orbital degrees o…
Renormalization of the electron-spin-fluctuation interaction in the t-t'-U Hubbard model
Z. B. Huang, W. Hanke, E. Arrigoni +1
We study the renormalization of the electron-spin-fluctuation (el-sp) vertex in a two-dimensional Hubbard model with nearest-neighbor (t) and next-nearest-neighbor (t') hopping by…
Antiferromagnetic to superconducting phase transition in the hole- and electron-doped Hubbard model at zero temperature
M. Aichhorn, E. Arrigoni, M. Potthoff +1
The competition between d-wave superconductivity (SC) and antiferromagnetism (AF) in the high-Tc cuprates is investigated by studying the hole- and electron-doped two-dimensional H…
Correlated band structure and the ground-state phase diagram in high-Tc cuprates
Werner Hanke, Markus Aichhorn, Enrico Arrigoni +1
We review results obtained with a recently proposed variational cluster approach (VCA) for the competition between d-wave superconductivity (dSC) and antiferromagnetism (AF) in the…
Correlated band structure of electron-doped cuprate materials
C. Dahnken, M. Potthoff, E. Arrigoni +1
We present a numerical study of the doping dependence of the spectral function of the n-type cuprates. Using a variational cluster-perturbation theory approach based upon the self-…
Antiferromagnetism and hole pair checkerboard in the vortex state of high Tc superconductors
Han-Dong Chen, Jiang-Ping Hu, Sylvain Capponi +2
We propose a microscopic state for the vortex phase of BSCO superconductors. Around the vortex core or above H_{c2}, the d wave hole pairs form a checkerboard localized in the comm…
