Fluctuation exchange study on the electron-hole asymmetry of the superconductivity across 1/3 filling in the trilayer Hubbard model
Yushi Yamada, Masataka Kakoi, Masayuki Ochi +1
We study within the fluctuation exchange approximation the trilayer Hubbard model where three layers of the Hubbard model are coupled by large interlayer hoppings so that the overl…

Pairing properties of correlated three-leg ladders with strong interchain couplings near 1/3 filling
Yushi Yamada, Tatsuya Kaneko, Masataka Kakoi +2
We investigate the ground-state properties of correlated three-leg ladders near 1/3 filling. We apply the density-matrix renormalization group method to the three-leg t-J ladder wi…
