Sažetak
We investigate the behaviour of multipartite entanglement in finite-size quantum spin systems, resorting to a hierarchy of geometric measures of multipartite entanglement recently introduced in the literature. In particular, we investigate the ground-state entanglement in the X Y model defined on finite chains of N sites with periodic boundary conditions. We analyse the behaviour of the geometric measures of (N − 1)-partite and (N /2)-partite entanglement and compare them with the Wei–Goldbart geometric measure of global entanglement.
