The discovery of neutrinoless β β decay could soon be within reach. This hypothetical
ultrarare nuclear decay offers a privileged portal to physics beyond the standard model of …

Nuclear weak decays provide important probes to fundamental symmetries in nature. A
precise description of these processes in atomic nuclei requires comprehensive knowledge …

Perturbative and non-perturbative expansion methods already constitute a tool of choice to
perform ab initio calculations over a significant part of the nuclear chart. In this context, the …

We present developments and applications for the diagonalization of shell-model
Hamiltonians in a discrete nonorthogonal basis. The method, and its actual numerical …

Shapes and shape evolution in the mass-130 region, including the Te, Xe, and Ba isotopes,
have long been a focus of discussion in nuclear physics. This mass region consists of …

The next years will see the completion of the radioactive ion beam facility SPES (Selective
Production of Exotic Species) and the upgrade of the accelerators complex at Istituto …

We study the shape coexistence in the nucleus Si 28 with the nuclear shell model using
numerical diagonalizations complemented with variational calculations based on the …

Background: Many quantal many-body methods that aim at the description of self-bound
nuclear or mesoscopic electronic systems make use of auxiliary wave functions that break …

We study the ability of variational approaches based on self-consistent mean-field and
beyond-mean-field methods to reproduce exact energies and electromagnetic properties of …

Strong octupole correlations have been observed in the low-lying states of atomic nuclei
across various mass regions. In this review, we provide an overview of Beyond Mean-Field …
