| 摘 要： | 在文中给出了库柏对的两种不同表达形式。发现用由对算符组成的哈密顿量来计算更方便,用这些对算符对易性质,而不是把它们看成费米子算符的组合产物。这样一来,研究的库柏对相互作用问题也把库柏对看成对算符。文中解决了两个库柏对相互作用问题,并讨论了推广到多库柏系统的情况。

| Abstract: | Two different expressions for Cooper pair number operator were presented.It was demonstrated that the calculations with a Hamiltonian expressed by pairon operators was more convenient using the commutation properties of these operators without presenting them as a product of fermion operators.This allows to study problems in which the interactions between Cooper pairs were also included.The problem with two interacting Cooper pairs was resolved. |
