Figure 1
The change in the ground-state wavefunction in the critical region is analysed considering dC(1)/d
as a function of the reduced coupling strength
.
Figure 2
The finite size scaling is performed for the case of logarithmic divergences22.

As in the case of the nearest-neighbour concurrence, data collapse is also obtained for the next-nearest-neighbour concurrence C(2).

The universality hypothesis for the entanglement is checked by considering the model hamiltonian, defined in equation (1), for a different value of
