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…
Extinction of impurity resonances in large-gap regions of inhomogeneous d-wave superconductors
Brian M. Andersen, S. Graser, P. J. Hirschfeld
Impurity resonances observed by scanning tunneling spectroscopy in the superconducting state have been used to deduce properties of the underlying pure state. Here we study a longs…
Determining gap nodal structures in Fe-based superconductors: angle-dependence of the low temperature specific heat in an applied magnetic field
S. Graser, G. R. Boyd, Chao Cao +3
Since the discovery of high-Tc LaO_1-xF_xFeAs, and other such systems based on FeAs layers, several proposals have been made for the superconducting order parameter Delta_k, on bot…
