Topological Multipartite Entanglement in a Fermi Liquid

We show that the topology of the Fermi sea of a D-dimensional Fermi gas is reflected in the multipartite entanglement characterizing D+1 regions that meet at a point. For odd D we introduce the multipartite mutual information and show that it exhibits a log^{D}L divergence as a function of system si...
