Local modulations of the spin-fluctuation mediated pairing interaction by impurities in d-wave superconductors
A. T. Roemer, S. Graser, T. S. Nunner +2
We present a self-consistent real space formulation of spin-fluctuation mediated d-wave pairing. By calculating all relevant inhomogeneous spin and charge susceptibilities in real…
d-wave pairing from spin fluctuations in the KxFe{2-y}Se2 superconductors
T. A. Maier, S. Graser, P. J. Hirschfeld +1
Angle-resolved photoemission spectroscopy measurements on the recently discovered superconduc- tors in the KFe2Se2 family with critical temperatures up to - 33K suggest that no Fer…
Pairing Theory of Striped Superconductivity
Florian Loder, Siegfried Graser, Arno P. Kampf +1
Striped high- superconductors such as LaNdSrCuO and LaBaCuO near show a fascinating competition between spin and charge…
Transport properties of 3D extended s-wave states in Fe-based superconductors
V. Mishra, S. Graser, P. J. Hirschfeld
The Fermi surfaces of Fe-pnictide superconductors are fairly two-dimensional (2D), and it has thus come as a surprise that recent penetration depth and thermal conductivity measure…
Symmetry of spin excitation spectra in the tetragonal paramagnetic and superconducting phases of 122-ferropnictides
J. T. Park, D. S. Inosov, A. Yaresko +16
We study the symmetry of spin excitation spectra in 122-ferropnictide superconductors by comparing the results of first-principles calculations with inelastic neutron scattering (I…
Effects of impurities and vortices on the low-energy spin excitations in high-Tc materials
Brian M. Andersen, Markus Schmid, Siegfried Graser +2
We review a theoretical scenario for the origin of the spin-glass phase of underdoped cuprate materials. In particular it is shown how disorder in a correlated d-wave superconducto…
