arXiv:quant-ph/0212120 · doi:10.1103/PhysRevA.67.054301
Abstract
We study a set of spatial bosonic modes localized on a graph The particles are allowed to tunnel from vertex to vertex by hopping along the edges of We analyze how, in the exact many-body eigenstates of the system i.e., Bose-Einstein condensates over single-particle eigenfunctions, the bi-partite quantum entanglement of a lattice vertex with respect to the rest of the graph depends on the topology of
