利用非平衡的格林函數技術的主方程，我們研究了Chern拓撲絕緣體中吸附原子雜質態的動力學。 我們研究了Chern拓撲絕緣體中吸附原子質態的動力學。
在這裡，我們考慮Haldane模型 是沒有外部磁場的Chern絕緣子模型，在費米能階。 由於無間隙譜能普密度，與初始雜質態將消散到Haldane模型上; 反之,非馬爾可夫動力學出現在雜質態耦合大塊石墨烯或沒有拓樸的一般絕緣體。 此外，我們可以利用雜質態的耗散和波動來探索相圖，以區分普通絕緣體和Chern絕緣體。 結果，我們發現了一些關於雜質非平衡動力學的有趣現象。

Using the master equation based on the non-equilibrium Green function technique[1],
we investigate the dynamics of adatom impurity state in Chern topological insulator.
we investigate the dynamics of adatom impurity state in Chern topological insulator.
Here we consider the Haldane model[2] as the one of Chern insulator model without the external magnetic field. At Fermi level, the initial impurity state coupling with the edge of non-trivial topological ribbon Haldane model will dissipate to the Haldane model because of gapless spectrum density; whereas the non-Markovian dynamics appears when the impurity state coupling the bulk Haldane model or normal insulator. Moreover, we can use the dissipation and fluctuation of impurity state to explore the phase diagram to differ normal insulator and Chern insulator. In turn, we find out some interesting phenomena about the non-equilibrium dynamics of impurity.
