| 中文摘要 | We propose an integrable model of one-dimensional interacting electrons coupled with the local orbitals arranged periodically in the chain. Since the local orbitals are introduced in a way that double occupation is forbidden, the model keeps the main features of the periodic Anderson model with an interacting host. For an attractive interaction, it is found that the local orbitals enhance the effective mass of the Cooper-pair-like singlets and also the pair correlation in the ground state. However, the persistent current is depressed in this case. For the repulsive interaction case, the Hamiltonian is non-Hermitian but allows Cooper pair solutions with small momenta, which are induced by the hybridization between the extended states and the local orbitals.
