    "abstract": "We speak of chaos in quantum systems if the statistical properties of the\neigenvalue spectrum coincide with predictions of random-matrix theory. Chaos is\na typical feature of atomic nuclei and other self-bound Fermi systems. How can\nthe existence of chaos be reconciled with the known dynamical features of\nspherical nuclei? Such nuclei are described by the shell model (a mean-field\ntheory) plus a residual interaction. We approach the question by using a\nstatistical approach (the two-body random ensemble): The matrix elements of the\nresidual interaction are taken to be random variables. We show that chaos is a\ngeneric feature of the ensemble and display some of its properties, emphasizing\nthose which differ from standard random-matrix theory. In particular, we\ndisplay the existence of correlations among spectra carrying different quantum\nnumbers. These are subject to experimental verification.",
