    "abstract": "The monogamous nature of entanglement has been illustrated by the derivation\nof entanglement sharing inequalities - bounds on the amount of entanglement\nthat can be shared amongst the various parts of a multipartite system.\nMotivated by recent studies of decoherence, we demonstrate an interesting\nmanifestation of this phenomena that arises in system-environment models where\nthere exists interactions between the modes or subsystems of the environment.\nWe investigate this phenomena in the spin-bath environment, constructing an\nentanglement sharing inequality bounding the entanglement between a central\nspin and the environment in terms of the pairwise entanglement between\nindividual bath spins. The relation of this result to decoherence will be\nillustrated using simplified system-bath models of decoherence.",
