Numerical Results for the Hubbard Model: Implications for the High Tc Pairing Mechanism

AbstractNumerical studies of the Hubbard model and its strong-coupling form, the t-J model, show evidence for antiferromagnetic, $$d_{x^{\text{2}} - y^2 } $$ -pairing and stripe correlations which remind one of phenomena seen in the layered cuprate materials. Here, we ask what these numerical results imply about various scenarios for the pairing mechanism.
