抜粋

Coexistence of the s and [formula omitted]-wave (d-wave) pairing is investigated in the two-dimensional (2-D) extended Hubbard model with on-site repulsive and inter-site attractive interactions using the mean-field approximation at T=0K. The next-nearest-neighbor hopping effect can induce the coexistence of the s and d-wave pairing. It is found that in such a case, s + id-wave pairing state becomes most stable.
