库柏对库柏对是指电子结合在一起的状态。一般来说，电子之间都有微小的引力，由此使得电子的能量低于费米能时，电子就会结合在一起，这一能量降低大约是1meV的量级，一般的温度对应热运动能量相对很大，因此库柏对的现象通常要在低温下超导状态才会出现。库柏对这个概念是的基础是由BCS理论创建，而这个理论是约翰·巴丁、利昂·库珀和约翰·施里弗这三人提出的，这也让他们三个人得到诺贝尔奖。

Cooper pair 库柏对In condensed matter physics, a Cooper pair or BCS pair is a pair of electrons (or other fermions) bound together at low temperatures in a certain manner first described in 1956 by American physicist Leon Cooper. Cooper showed that an arbitrarily small attraction between electrons in a metal can cause a paired state of electrons to have a lower energy than the Fermi energy, which implies that the pair is bound. In conventional superconductors, this attraction is due to the electron–phonon interaction. The Cooper pair state is responsible for superconductivity, as described in the BCS theory developed by John Bardeen, Leon Cooper, and John Schrieffer for which they shared the 1972 Nobel Prize. |
