Entanglement in the scattering process by the spin impurity
Dong Yang, Shi-Jian Gu, Haibin Li
We study entanglement in the scattering processes by the spin-fixed impurity and the Kondo impurity, respectively. 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.
