Competition between antiferromagnetic and charge-density-wave order in the half-filled Hubbard-Holstein model.
Phys Rev Lett

Department of Physics, Stanford University, Stanford, California 94305, USA.
We present a determinant quantum Monte Carlo study of the competition between instantaneous on-site Coulomb repulsion and retarded phonon-mediated attraction between electrons, as described by the two-dimensional Hubbard-Holstein model. At half filling, we find a strong competition between antiferromagnetism (AFM) and charge-density-wave (CDW) order. We demonstrate that a simple picture of AFM-CDW competition that incorporates the phonon-mediated attraction into an effective-U Hubbard model requires significant refinement.
