Crossover of superconducting properties and kinetic-energy gain in two-dimensional Hubbard model

Hisatoshi Yokoyama, Yukio Tanaka, Masao Ogata +1

Superconductivity in the Hubbard model on a square lattice near half filling is studied using an optimization (or correlated) variational Monte Carlo method. Second-order processes…
