Title:     Ab Initio Approaches to Correlations in Nuclei and their Applications

Abstract: Correlations - intended as multiple-nucleon mechanisms that cannot be modelled by a pure mean-field potential - are the backbone of our deeper understanding of atomic nuclei. They are manifest in the fragmentation of the spectral strength which is encountered in one-nucleon addition and removal measurements.

  In recent years, we have advanced high-performance computational many-body techniques, such as propagator theory, that can be used to compute the spectral function but that also allow meaningful predictions of radii and binding energies up to masses of A~100.   This talk will review such progress and aim at giving a broader perspective of ab initio theory, in which large scale computations are not only used to benchmark the theories of nuclear forces but they can also help to constrain our insight about nuclear phenomena. I will further discuss some cases in which the knowledge of the spectral function is important to predict, e.g., the interplay between structure and reactions and the response to neutrinos under the wide range of energies relevant to oscillation experiments.
