采用电子相互作用的g模型,在RPA中研究了多并苯材料正常分子轨道态的不稳定性。预测的凝聚态为单重态超导(SSC)、电荷密度波(CDW)和自旋密度波(SDW),并给出了它们的相图。与通常的一维(1D)导体相比,它揭示了广泛的超导态,这是CDW转变所不能克服的。与聚乙炔的情况相比,本模型的Peierls失真的弱点也被对比。
The instabilities of a normal molecular orbital state of polyacenic materials are studied within RPA with a g model for an electronic interaction. The condensed states predicted are singlet superconducting (SSC), charge density wave (CDW), and spin density wave (SDW) ones, and their phase diagram is shown. In contrast to usual one‐dimensional (1D) conductors, there reveals a wide range of superconducting state, which is not overcome by CDW transition. Weakness of Peierls distortion of the present model is also contrasted with the case of polyacetylene.
