    "abstract": "We study the relation between entanglement and quantum chaos in one- and\ntwo-dimensional spin-1/2 lattice models, which exhibit mixing of the\nnoninteracting eigenfunctions and transition from integrability to quantum\nchaos. Contrary to what occurs in a quantum phase transition, the onset of\nquantum chaos is not a property of the ground state but take place for any\ntypical many-spin quantum state. We study bipartite and pairwise entanglement\nmeasures, namely the reduced Von Neumann entropy and the concurrence, and\ndiscuss quantum entanglement sharing. Our results suggest that the behavior of\nthe entanglement is related to the mixing of the eigenfunctions rather than to\nthe transition to chaos.",
