Macroscopic Observables Detecting Genuine Multipartite Entanglement in
Many Body Systems    [PDF]

Andreas Gabriel, Beatrix C. Hiesmayr

We show a general approach for detecting genuine multipartite entanglement in many-bodysystems by means of macroscopic observables (such as the energy) only. We show that the obtained criteria detect large areas of genuine multipartite entanglement in typical many body states, which are not detected by other criteria.
