Quantifying entanglement via static structure factors — •Hermann Kampermann1, Marcus Cramer2, Fabian Wolf1, Oliver Marty2, Alexander Streltsov1, Martin Plenio2, and Dagmar Bruß11Institut für theoretische Physik III, Universität Düsseldorf, Germany — 2Institut für theoretische Physik, Universität Ulm, Germany

The static structure factor is a global and accessible observable in experimental setups like e.g. in neutron scattering. Recently it was shown how to use such structure factors as entanglement witnesses and entanglement monotones [1,2]. We generalize these concepts to structure factors with arbitrary spin, and compare different types of witnesses as well as entanglement monotones.
