Abstract:

We investigate the scaling properties of the excitation energies and transition amplitudes of the one-dimensional spin-\(\) antiferromagnetic Heisenberg model exposed to an external perturbation. Two types of perturbations are discussed in detail: a staggered field and a dimerized field.
