Competition between Antiferromagnetism and Superconductivity in High $T_c$ Cuprates

David Senechal, P. -L. Lavertu, M. -A. Marois +1

Using variational cluster perturbation theory we study the competition between d-wave superconductivity (dSC) and antiferromagnetism (AF) in the the t-t'-t''-U Hubbard model. Large…
