Finally, I will introduce the use of a geometric measure of block bipartite entanglement that allows to identify a hierarchy of &#8216;inversion points&#8217; in the ordering of the reduced k-body states in the ground state of quantum spin systems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I will review some recent work carried out in Salerno on the investigation of quantum many-body systems from the viewpoint of quantum information theory.
