Anisotropic quasiparticle lifetimes in Fe-based superconductors
A. F. Kemper, M. M. Korshunov, T. P. Devereaux +3
We study the dynamical quasiparticle scattering by spin and charge fluctuations in Fe-based pnictides within a five-orbital model with on-site interactions. The leading contributio…
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…
Magnetic correlations on the full chains of Ortho-II YBaCuO
W. Chen, P. J. Hirschfeld
We propose that the NMR line shape on the chain Cu in the stoichiometric high- superconductor Ortho-II YBaCuO is determined by the magnetization induced on Cu…
Inversion of specific heat oscillations with in-plane magnetic field angle in 2D d-wave superconductors
G. R. Boyd, P. J. Hirschfeld, I. Vekhter +1
Experiments on several novel superconducting compounds have observed oscillations of the specific heat when an applied magnetic field is rotated with respect to the crystal axes. T…
