Description

The atomic nucleus is a complex many-body system where simple collective features can emerge from the interaction between its constituent particles. For example, some energy levels are sorted out in bands that can be described in terms of rotations and/or vibrations around an intrinsic shape of the nucleus as a whole. The description of these aspects from a microscopic point of view is still a challenge for modeling the atomic nucleus.  In this seminar I will present recent developments and applications of the symmetry conserving configuration mixing method based on the Gogny energy density functional. In particular, I will discuss the inclusion of intrinsically rotating wave functions (cranking) to describe collective and single-particle features at the same time in the nucleus 44S. Additionally, I will show some results of octupole deformed nuclei, like the Barium isotopes above the N=82 shell closure.
