The impurities make the equal pairwise entanglement in a ring compete with each other so that the pairwise entanglement exhibits oscillation. If the impurities are of larger couplings, both the critical temperature and pairwise entanglement can be improved4 pages, 6 figuresQuantum PhysicsMulti-impurity effects on the entanglement of anisotropic Heisenberg ring XXZ under a homogeneous magnetic fieldtext
