论文摘要

我们使用密度矩阵重新归一化组方法研究了拓扑和围绕效应与非平凡传导带的相互作用。通过分析密度曲线,局部杂交和自旋/电荷间隙,我们发现,近距效应可能会通过链式的边缘在链的边缘上被拓扑末端状态在有限的临界临界近关系耦合下方造成$ j_ {k}^{c} $。我们构建一个表征末端状态过渡的相图。

We investigate the interplay of the topological and Kondo effects in a one-dimensional Kondo-Heisenberg model with nontrivial conduction band using the density matrix renormalization group method. By analyzing the density profile, the local hybridization, and the spin/charge gap, we find that the Kondo effect can be destructed at the edges of the chain by the topological end state below a finite critical Kondo coupling $J_{K}^{c}$. We construct a phase diagram characterizing the transition of the end states.
