Theoretical study of spin-fluctuation-mediated superconductivity in two-dimensional Hubbard models with an incipient flat band
Tetsuaki Aida, Karin Matsumoto, Daisuke Ogura +2
One promising way to enhance superconductivity is to have coexisting wide and incipient narrow bands, where the Fermi level intersecting the wide band lies just above the narrow ba…
Strongly enhanced superconductivity due to finite energy spin fluctuations induced by an incipient band : a FLEX study on the bilayer Hubbard model with vertical and diagonal interlayer hoppings
Karin Matsumoto, Daisuke Ogura, Kazuhiko Kuroki
We study the spin-fluctuation-mediated -wave superconductivity in the bilayer Hubbard model with vertical and diagonal interlayer hoppings. As in the two-leg ladder model wit…
Wide applicability of high pairing originating from coexisting wide and incipient narrow bands in quasi one dimension
Karin Matsumoto, Daisuke Ogura, Kazuhiko Kuroki
We study superconductivity in the Hubbard model on various quasi-one-dimensional lattices with coexisting wide and narrow bands originating from multiple sites within a unit cell,…
