Phys. Rev. A 67, 054301 (2003) [4 pages]Bipartite mode entanglement of bosonic condensates on tunneling graphsReceived 20 December 2002; published 20 May 2003 We study a set of L spatial bosonic modes localized on a graph Γ. The particles are allowed to tunnel from vertex to vertex by hopping along the edges of Γ. We analyze how, in the exact many-body eigenstates of the system, i.e., Bose-Einstein condensates over single-particle eigenfunctions, the bipartite quantum entanglement of a graph vertex with respect to the rest of the graph depends on the topology of Γ. © 2003 The American Physical Society URL:
