Weak ferromagnetism and other instabilities of the two-dimensional t-t' Hubbard model at Van Hove fillings

V. Hankevych, B. Kyung, A. -M. S. Tremblay

We investigate magnetic and superconducting instabilities of the two-dimensional t-t' Hubbard model on a square lattice at Van Hove densities from weak to intermediate coupling by…
