Theoretical Nuclear Physics Group

This research group investigates different highly topical subjects in Theoretical Nuclear Physics. This is a work on basic research which faces problems related to nuclear structure, reactions and decay properties of exotic nuclei. The main general goal is to develop theoretical models that could be applied to nuclei far from the valley of stability and to rare nuclear processes. This research has relevant connections with Astrophysics or Physics of Elementary Particles. Furthermore, some of the models can be applied to different fields, like Atomic Physics or Molecular Physics. The subjects to be investigated are also relevant to the modern radioactive beam facilities in operation or under construction, particularly so to FAIR.

Research

Our research scope covers all those aspects of nuclear structure, reactions, and decay properties of exotic nuclei with both, theoretical and experimental interest.

Light Nuclei: Halos and Borromean Systems

We investigate the properties of light nuclei in the proximity of the neutron and proton driplines. We compute bound states, resonances (complex scaling method), and continuum states.

Publications

Efimov effect

The Efimov effect in three dimensions is characterized by a three-body system, where the two-body s-wave scattering lengths for at least two of the three pairs are infinitely large, and consequently infinitely many bound three-body states can be found.

Publications

Nuclear Reactions with Astrophysical Interest

Exotic nuclei play a relevant role in stellar nucleosynthesis processes. A proper description of these reactions is essential to understand the production and abundance of the different elements in the Universe.

Publications

Particle confinement and non-integer dimensions

A continuous transition for a system moving in a 3D space to a lower dimensional space can be made by means of an external squeezing potential. We investigate the connection between this procedure and the use of the dimension d as a parameter that changes continuously from d=3 to d=1.

Publications

Combined few-body and mean-field model for nuclei

We combine few- and many-body degrees of freedom in a new computationally efficient model applicable to both bound and continuum states and adaptable to different subfields of physics.

Publications

Beta-decay and nuclear shape

We study beta-decay properties (Gamow-Teller strength distributions, half-lives, and beta-delayed nucleon emission probabilities) in deformed proton- and neutron-rich nuclei. We also study double beta-decay processes.

Publications

Weak-decay rates in astrophysical scenarios

Weak-decay rates are studied in astrophysical conditions of densities and temperatures that include the nucleosynthesis r- and rp-processes. Waiting-point nuclei are particularly considered.

Publications

Electron scattering from nuclei

We study electron scattering (elastic, inelastic and quasi-elastic) from deformed stable and exotic nuclei. We include longitudinal (Coulomb) and transverse (electric and magnetic) multipoles. Parity-violating electron scattering is also studied.

Publications

Nuclear structure evolution

We study the isotopic and isotonic evolution of nuclear ground state properties (masses, radii, shapes,...), as well as spectroscopic properties (excitation energies and transition probabilities) as the number of nucleons changes.
