排斥型有效互作用下的超导电性
Superconductivity in effective repulsive interaction
【摘要】 分析了电子间在有效排斥互作用下的超导电性.发现当能带宽度W>Ec,o()时,存在电子对;当W<Ec,o时,电子对消失.从而认为在电子对消失的区域,描写超导电性的应该是某种准粒子对,而不是电子对.
【Abstract】 The superconductivity in effective repulsive interaction between two electrons is considered. It is discovered that the electron pairs appear with energy band Width W>Ec,0 (Ec,0 = e); and they disappear with W<Ec,0 Therefore it is believed that superconductivity should be demonstrated with quasiparticle pairs in region where electron pairs disappear.
