Evolution of Topological End States in the One-Dimensional Kondo-Heisenberg Model with Site Modulation
Evolution of Topological End States in the One-Dimensional Kondo-Heisenberg Model with Site Modulation
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 …
