Incommensurability Effects in Odd Length J_1-J_2 Quantum Spin Chains: On-site magnetization and Entanglement

Andreas Deschner, Erik S. Sørensen

For the antiferromagnetic J_1-J_2 quantum spin chain with an even number of sites, the point J_2^d=1/2 J_1 is a disorder point. It marks the onset of incommensurate real space corr…

Impurity Entanglement in the $J - J_{2} - δ$ Quantum Spin Chain

Andreas Deschner, Erik S. Sorensen

The contribution to the entanglement of an impurity attached to one end of a $J - J_{2} - d e l t a$ quantum spin chain (S=1/2) is studied. Two different measures of the impurity contributio…
