Abstract: W45.00003 : Topological signatures of Multipartite Entanglement
(Division of Condensed Matter, Max Planck Institute for the Physics of Complex Systems)
By means of Monte Carlo calculations, we study checkerboard, stripe, valence-bond solids, Z2 topologically ordered spin liquid, and superfluid phase. We find that each ground-state is characterized by a certain `topological spectrum' which can be used to differentiate among different ground-states.
