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…

Exceptional points in the one-dimensional Hubbard model
Roman Rausch, Robert Peters, Tsuneya Yoshida
Non-Hermitian phenomena offer a novel approach to analyze and interpret spectra in the presence of interactions. Using the density-matrix renormalization group (DMRG), we demonstra…

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…
