- 論文の詳細を見る
We investigate the effect of interchain repulsive interaction on the pairing symmetry competition in quasi-one-dimensional organic superconductors (TMTSF)_2X by applying random phase approximation and quantum Monte Carlo calculation to an extended Hubbard model. We find that interchain repulsive interaction enhances the 2k_F charge fluctuations, thereby making the possibility of spin-triplet f-wave pairing dominating over spin-singlet d-wave pairing realistic.
