Query: Mode Entanglement and Entangling power in Bosonic Graphs   We analyze the quantum entanglement properties of bosonic particles hopping
over graph structures.Mode-entanglement of a graph vertex with respect the rest
of the graph is generated, starting from a product state, by turning on for a
finite time a tunneling along the graph edges. The maximum achieved during the
dynamical evolution by this bi-partite entanglement characterizes the
entangling power of a given hopping hamiltonian. We studied this entangling
power as a function of the self-interaction parameters i.e., non-linearities,
for all the graphs up to four vertices and for two different natural choices of
the initial state. The role of graph topology and self-interaction strengths in
optimizing entanglement generation is extensively studied by means of exact
numerical simulations and by perturbative calculations.
