  title = {Critical scaling at the N{\'e}el transition in an extended Hubbard model with Ising-like interaction},
  abstract = {We examine the critical behavior of the von Neumann entanglement entropy and the staggered magnetization order parameter in an extended Hubbard chain across the N{\'e}el transition at half-filling. The order parameter and the entanglement entropy was calculated using density matrix renormalization group (DMRG) for periodic chains with length L = 32, 64, and 100. We demonstrate that the entanglement entropy can locate the quantum critical point. Finite size scaling analyses of the N{\'e}el order parameter and entanglement entropy give estimates for the critical exponents associated with these observables.},
