本文应用随机相位近似和量子蒙特卡罗计算对扩展的Hubbard模型研究了链间排斥相互作用对准一维有机超导体（TMTSF） 2x中配对对称竞争的影响。我们发现链间排斥性相互作用增强了2k电荷波动，从而使自旋三重态F波配对优于自旋单线态d波配对的可能性成为现实。
We investigate the effect of interchain repulsive interaction on the pairing symmetry competition in quasi-one-dimensional organic superconductors (TMTSF) 2 X by applying random phase approximation and quantum Monte Carlo calculation to an extended Hubbard model. We find that interchain repulsive interaction enhances the 2 k F charge fluctuations, thereby making the possibility of spin-triplet f -wave pairing dominating over spin-singlet d -wave pairing realistic.
