| 摘 要： | 研究了自由电子与固定杂质自旋的散射过程中的纠缠行为.研究发现,固定自旋的杂质能起到纠缠过滤器的作用,实现自由电子间的纠缠浓缩.当两无相互作用的电子先后经过同一Kondo杂质并与之发生散射时,可以使得原本不纠缠的电子发生纠缠.类似地,当运动的电子先后经过两无相互作用的Kondo杂质并与它们发生散射,可以使得原本不纠缠的K...

| Abstract: | The entanglement in the scattering processes by the spin-fixed impurity and the Kondo impurity is investigated,respectivel y.The spin-fixed impurity is employed as a filter to concentrate entanglement. One Kondo impurity can create entanglement between two noninteracting particles and one scattered particle can do so between two noninteracting Kondo impurities. |
