Achieving a first-principles description of the interaction of nuclei with external probes is a fundamental, yet challenging, problem, that bears implications to our understanding of the internal structure of nuclei and of the nuclear matter equation of state.

In this talk, I will present developments in the coupled-cluster framework that enable us to determine the response of open-shell nuclei near magicity [1]. I will focus on electric dipole excitations and discuss predictions for the electric dipole polarizability and the photonuclear cross sections.

In the second part of the seminar, I will then discuss state-of-the-art predictions for the nuclear matter equation of state determined with a recently introduced Green’s function approach [2].
