    "abstract": "We consider the ground-state entanglement in highly connected many-body\nsystems, consisting of harmonic oscillators and spin-1/2 systems. Varying their\ndegree of connectivity, we investigate the interplay between the enhancement of\nentanglement, due to connections, and its frustration, due to monogamy\nconstraints. Remarkably, we see that in many situations the degree of\nentanglement in a highly connected system is essentially of the same order as\nin a low connected one. We also identify instances in which the entanglement\ndecreases as the degree of connectivity increases.",
