Doping-induced crossovers between the dominant pairing correlations in the extended Hubbard model

We examine the influence of hole doping on superconducting pairing symmetries in the two-dimensional Hubbard model extended by next-nearest-neighbor hopping, nearest-neighbor Coulomb interaction, correlated hopping, exchange interaction, and pair-hopping processes. Using Lanczos exact diagonalization supported by proje...
