On the Kinetic Energy Driven Superconductivity in the Two-Dimensional Hubbard Model
We investigate the role of kinetic energy for the stability of superconducting state in the two-dimensional Hubbard model on the basis of an optimization variational Monte Carlo method. The wave function is optimized by multiplying by correlation operators of site off-diagonal type. This wave functi...
