Effect of disorder on sign reversing s-wave pair state for Fe-pnictides
ORAL
Abstract
In this work, we consider a phenomenological model for sign changing s-wave order parameters appropriate for the ferropnictide superconductors. We consider both magnetic and non-magnetic impurities within the Born approximation, and study the effects of this disorder on transport properties in superconducting state. We compare our results with experimental data for Fe-pnictides, where such a sign-changing s-wave state may be realized.
