Abstract: | We propose a scheme to enhance the entanglement of a dissipative system, and the enhancement is happened during certain intervals of the evolution time. Our method is obtained by introducing one impurity into a Heisenberg XY chain and then solving the Lindblad form of the master equation with different initial states. The dynamics of entanglement reveal that one can significantly enhance the entanglement. This result will be helpful for the generation and transportation of entanglement in real solid-state systems. |
