Triplet superconductor

For the single chain (w = w2 = 0), there are seven two-particle correlation functions, four of which are divergent. The divergent ones are the CDW (charge-density wave), SDW (spin-density wave), SS (singlet superconductor), and TS (triplet superconductor) response functions and are shown in Fig. (3). The... 

Manifestation of Triplet Superconductivity in Superconductor-Ferromagnet Structures... 

In summary we showed experimental results and theoretical calculations on magnetization orientation dependence of superconductor critical temperature in F/S/F all-metallic structures. This effect is based on the emergence of a small admixture of spin-triplet superconductivity in the hybrid... 

To conclude, we have shown that the specific shape of Hc2(T) observed in the cobalt oxide superconductor can be explained in terms of the field-induced transition from singlet to triplet pairing. This scenario assumes a competition between singlet and triplet types of superconductivity, which remains in... 

Thus, at least for UPta, there is a coexistence of superconductivity and spin fluctuations. This is contrary to the singlet-state, electron-electron coupling of the BCS model for superconductivity, but not for a triplet ground-state [65,67]. This type of fermion pairing is seen in superfluid He, but nowhere else in condensed-matter systems. The existence of spin fluctuations in the other heavy fermion superconductors is not confirmed. The strongest evidence for triplet-pairing occurs in UBeja and UPta [68].
