摘要：

We present a one-dimensional model of electrons coupled to localized moments of spin S greater than or equal to 1 in which magnetism and superconductivity interplay in a nontrivial manner. This model has a non-Fermi-liquid ground state of the chiral spin liquid type. An unconventional odd-frequency pairing is shown to be the dominant instability of the system, together with antiferromagnetism of the local moments. We argue that this model captures the physics of the Kondo-Heisenberg spin S = 1 chain, in the limit of strong Kondo coupling. Finally, we discuss briefly the effect of interchain coupling.
