    "abstract": "We analyze the quantum entanglement properties of bosonic particles hopping\nover graph structures.Mode-entanglement of a graph vertex with respect the rest\nof the graph is generated, starting from a product state, by turning on for a\nfinite time a tunneling along the graph edges. The maximum achieved during the\ndynamical evolution by this bi-partite entanglement characterizes the\nentangling power of a given hopping hamiltonian. We studied this entangling\npower as a function of the self-interaction parameters i.e., non-linearities,\nfor all the graphs up to four vertices and for two different natural choices of\nthe initial state. The role of graph topology and self-interaction strengths in\noptimizing entanglement generation is extensively studied by means of exact\nnumerical simulations and by perturbative calculations.",
