t'- and t"-dependence of the bulk-limit superconducting condensation energy of the 2D Hubbard model

K. Yamaji, T. Yanagisawa, M. Miyazaki +1

The 2D Hubbard model having the 2nd- and 3rd-neighbor transfer energies t' and t" is investigated by use of the variational Monte Carlo method. At the nearly optimal doping with on…
