    "abstract": "We study multipartite entanglement measures for a one-dimensional Ising chain\nthat is capable of showing both integrable and nonintegrable behaviour. This\nmodel includes the kicked transverse Ising model, which we solve exactly using\nthe Jordan-Wigner transform, as well as nonintegrable and mixing regimes. The\ncluster states arise as a special case and we show that while one measure of\nentanglement is large, another measure can be exponentially small, while\nsymmetrizing these states with respect to up and down spins, produces those\nwith large entanglement content uniformly. We also calculate exactly some\nentanglement measures for the nontrivial but integrable case of the kicked\ntransverse Ising model. In the nonintegrable case we begin on extensive\nnumerical studies that shows that large multipartite entanglement is\naccompanied by diminishing two-body correlations, and that time averaged\nmultipartite entanglement measures can be enhanced in nonintegrable systems.",
