摘要：

We investigate interplay of 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 edges of the chain by the topological end state below a finite critical Kondo coupling JK~C.We construct a phase diagram characterizing the transition of the end states.
