This event is part of the Condensed Matter Theory Seminar Series.

Abstract: We construct a two-leg ladder model of an Fe-pnictide superconductor and discuss its properties and relationship with the familiar two-leg cuprate model. Our results suggest that the underlying pairing mechanism for the Fe-pnictide superconductors is similar to that for the cuprates. A
two-orbital extension of this ladder model allows us to study the pairing symmetry and nematic ordering in the Fe pnictides.
