Entanglement convertibility by sweeping through the quantum phases of the alternating bonds XXZ chain
We study the entanglement structure and the topological edge states of the ground state of the spin-1/2 XXZ model with bond alternation. We employ parity-density matrix renormalization group with periodic boundary conditions. The finite-size scaling of Rényi entropies S(2) and S(∞) are used to const...
