Itinerant magnetism in the triangular lattice Hubbard model at half-doping: Application to twisted transition-metal dichalcogenides
Yuchi He, Roman Rausch, Matthias Peschke +4
We use unrestricted Hartree-Fock, density matrix renormalization group, and variational projected entangled pair state calculations to investigate the ground state phase diagram of…

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…
