Many-variable variational Monte Carlo study of superconductivity in two-band Hubbard models with an incipient band

We study superconductivity in two-band models where one of the bands does or does not intersect the Fermi level depending on the parameter values. Applying a many-variable variational Monte Carlo method for a Hubbard model on two-leg ladder and bilayer square lattices, we show that superconductivity...
