摘要: 基于分形振子(fracton)-电子相互作用,提出了一个无序超导的动力学理论;证明了无序超导体中的电子通过交换虚分形振子可能产生一个有效的吸引作用,它使得具有相反波矢和自旋的电子组成库珀对,从而导致超导。本理论从动力学观点导出了渗流超导的临界温度。
Abstract: The dynamic theory for disordered superconductivity is suggested based on the fracton-electron interaction. It has been demonstrated that electrons in disordered superconductors can feel an attractive interaction by exchange of virtual fractons. A normal state is unstable with respect to such an interaction, and a superconducting state is formed through the association of electrons in pairs with opposite wave vectors and spins. The critical temperature for percolation superconducting model can be derived from this theory.
