Dual Fermions + Disorder — •Patrick Haase¹, Hanna Terletska², Shuxiang Yang², Thomas Pruschke¹, and Mark Jarrell² — ¹Georg-August Universität Göttingen — ²Louisiana State University

We introduce an extension of the Dual Fermion formalism that allows to tread disordered interacting systems. To derive the formalism, the Replica trick is used. We will show data that compares the method to results obtained within the coherent potential approximation and the dynamical cluster approximation.
