The antiferromagnetic Heisenberg model on the fullerene geometry
Roman Rausch, Cassian Plorin, Matthias Peschke
We solve the quantum-mechanical antiferromagnetic Heisenberg model with spins positioned on vertices of the truncated icosahedron using the density-matrix renormalization group (DM…

Kondo Screening and Indirect Magnetic Exchange through a Conventional Superconductor Studied by the Density-Matrix Renormalization Group
Cassian Plorin, Michael Potthoff
The competition between the Kondo screening and indirect magnetic exchange in systems with two magnetic impurities coupled to a conventional s-wave superconductor gives rise to a n…
