在本文中,我们提出并定量地检验了耗散对拓扑系统的影响。我们使用具有现场欧姆耗散的Kitaev量子线的特定模型,并执行数值精确方法来研究零温度下耗散对系统拓扑特征(例如Majorana边缘模式)的影响。我们发现,尽管拓扑相位对弱耗散具有鲁棒性,但根据系统的对称性,它最终将通过连续量子相变或交叉被足够强的耗散所破坏。讨论了耗散驱动的量子临界。
In this paper, we formulate and quantitatively examine the effect of dissipation on topological systems. We use a specific model of Kitaev quantum wire with an onsite Ohmic dissipation and perform a numerically exact method to investigate the effect of dissipation on the topological features of the system (e.g., the Majorana edge mode) at zero temperature. We find that even though the topological phase is robust against weak dissipation as it is supposed to be, it will eventually be destroyed by sufficiently strong dissipation via either a continuous quantum phase transition or a crossover depending on the symmetry of the system. The dissipation-driven quantum criticality has also been discussed.
