Entanglement entropies of the quarter filled Hubbard model

We study Rényi and von Neumann entanglement entropies in the ground state of the one dimensional quarter-filled Hubbard model with periodic boundary conditions. We show that they exhibit an unexpected dependence on system size: for L = 4 mod 8 the results are in agreement with expectations based on...
