Abstract

The effects of alternating interaction on the bipartite entanglement are considered in an antiferromagnetic Heisenberg opened chain Entropy is used to evaluate bipartite entanglement in the system There are large oscillations between even and odd Lvalues entropy The even oddvalues entropy increases when the length of the subsystem increases The method of density matrix renormalizationgroup is applied to obtain logarithmic behavior of entropy
