The antiferromagnetic $S = 1/2$ Heisenberg model on the $C_{60}$ 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…

Topological phases arising from attractive interaction and pair hopping in the Extended Hubbard Model

Roman Rausch, Matthias Peschke

The extended Hubbard model with an attractive density-density interaction, positive pair hopping, or both, is shown to host topological phases, with a doubly degenerate entanglemen…
