Using Space Group Representations to Unfold the Bandstructures of Iron Pnictides — •Milan Tomic, Roser Valentí, and Harald Jeschke — Institut für Theoretische Physik, Goethe-Universität, Frankfurt am Main, Germany

We present a general method for unfolding bandstructures beyond the limit of translational symmetry, utilizing irreducible representations of space groups. We demonstrate the method on the representative materials of 11 and 122 iron-pnictide family and discuss the result in context of ARPES experiments.
