Entanglement of bosonic modes in symmetric graphs
M. Asoudeh, V. Karimipour
abstract: The ground and thermal states of a quadratic hamiltonian representing the
interaction of bosonic modes or particles are always Gaussian states. We
investigate the entanglement properties of these states for the case where the
interactions are represented by harmonic forces acting along the edges of
symmetric graphs, i.e. 1, 2, and 3 dimensional rectangular lattices, mean field
clusters and platonic solids. We determine the Entanglement of Formation (EoF)
as a function of the interaction strength, calculate the maximum EoF in each
case and compare these values with the bounds found in \cite{wolf} which are
valid for any quadratic hamiltonian.
