Large-scale numerical investigations of the antifderromagnetic Heisenberg icosidodecahedron — Jörg Ummethum¹, Andreas Läuchli², and •Jürgen Schnack¹ — ¹Bielefeld University, P.O. box 100131, D-33501 Bielefeld — ²Innsbruck University, Technikerstr. 25, A-6020 Innsbruck

We present up to date investigations of the antiferromagnetic Heisenberg icosidodecahedron by means of the Density Matrix Renormalization Group method. We compare our results with modern Correlator Product State as well as Lanczos calculations.
