Energy of bond defects in quantum spin chains obtained from local approximations and from exact diagonalization

open access: yes, 2007
We study the influence of ferromagnetic and antiferromagnetic bond defects on the ground-state energy of antiferromagnetic spin chains. In the absence of translational invariance, the energy spectrum of the full Hamiltonian is obtained numerically, by an
