    "abstract": "The ground and thermal states of a quadratic hamiltonian representing the\ninteraction of bosonic modes or particles are always Gaussian states. We\ninvestigate the entanglement properties of these states for the case where the\ninteractions are represented by harmonic forces acting along the edges of\nsymmetric graphs, i.e. 1, 2, and 3 dimensional rectangular lattices, mean field\nclusters and platonic solids. We determine the Entanglement of Formation (EoF)\nas a function of the interaction strength, calculate the maximum EoF in each\ncase and compare these values with the bounds found in \\cite{wolf} which are\nvalid for any quadratic hamiltonian.",
