    "abstract": "The dynamics of monopole giant resonances in nuclei is analyzed in the\ntime-dependent relativistic mean-field model. The phase spaces of isoscalar and\nisovector collective oscillations are reconstructed from the time-series of\ndynamical variables that characterize the proton and neutron density\ndistributions. The analysis of the resulting recurrence plots and correlation\ndimensions indicate regular motion for the isoscalar mode, and chaotic dynamics\nfor the isovector oscillations. Information-theoretic functionals identify and\nquantify the nonlinear dynamics of giant resonances in quantum systems that\nhave spatial as well as temporal structure.",
