Superconductivity in striped and multi-Fermi-surface Hubbard models: From the cuprates to the pnictides
Thomas A. Maier
Single- and multi-band Hubbard models have been found to describe many of the complex phenomena that are observed in the cuprate and iron-based high-temperature superconductors. Si…
Electron doping evolution of the anisotropic spin excitations in BaFe2-xNixAs2
Huiqian Luo, Zahra Yamani, Yanchao Chen +7
We use inelastic neutron scattering to systematically investigate the Ni-doping evolution of the low-energy spin excitations in BaFe2-xNixAs2 spanning from underdoped antiferromagn…
Pair Structure and the Pairing Interaction in a Bilayer Hubbard Model
T. A. Maier, D. J. Scalapino
The bilayer Hubbard model with an intra-layer hopping and an inter-layer hopping provides an interesting testing ground for several aspects of what has been called un…
Neutron Scattering Resonance and the Fe-pnictide Superconducting Gap
T. A. Maier, S. Graser, D. J. Scalapino +1
The existence of a neutron scattering resonance at a wavevector q* implies a sign change of the gap between two Fermi surface regions separated by wavevector q* . For the Fe pnicti…
Lifting of nodes by disorder in extended- state superconductors: application to ferropnictides
V. Mishra, G. Boyd, S. Graser +3
We show, using a simple model, how ordinary disorder can gap an extended- () symmetry superconducting state with nodes. The concommitant crossover of thermodynamic prope…
Near-degeneracy of several pairing channels in multiorbital models for the Fe-pnictides
S. Graser, T. A. Maier, P. J. Hirschfeld +1
Weak-coupling approaches to the pairing problem in the iron pnictide superconductors have predicted a wide variety of superconducting ground states. We argue here that this is due…
