The Hubbard model with fermionic tensor networks
Manuel Schneider, Johann Ostmeyer, Karl Jansen +2
Many electromagnetic properties of graphene can be described by the Hubbard model on a honeycomb lattice. However, this system suffers strongly from the sign problem if a chemical…

Simulating both parity sectors of the Hubbard Model with Tensor Networks
Manuel Schneider, Johann Ostmeyer, Karl Jansen +2
Tensor networks are a powerful tool to simulate a variety of different physical models, including those that suffer from the sign problem in Monte Carlo simulations. The Hubbard mo…
