Abstract:We present the multi-band dual triply irreducible local expansion (D-TRILEX) approach to interacting electronic systems and discuss its numerical implementation. This method is designed for a self-consistent description of multi-orbital systems that can also have several atoms in the unit cell. The current implementation of the D-TRILEX approach is able to account for the frequency-and channel-dependent long-ranged electronic interactions. We show that our method is accurate when applied to small multi-band sy… Show more
