Theoretical Nuclear Physics Group
Group Members
- Eirini Mavrommatis, Associate Professor (Ret.)
- Collaborators: Graduate and undergraduate students, UoA professors and Researchers from Greece and abroad (USA, Italy, Germany, Austria, Ukraine).
Short Description
The group is active in research mainly on Theoretical Nuclear Physics (studies of nuclei and multi-nucleon system of nuclear matter and neutron matter). This is closely related to Nuclear Astrophysics, Many-Body Theory, Complex Systems Theory and Artificial Intelligence. It comprises mainly the following two fields:
- Microscopic theory of multi-nucleon systems: Study of correlations (short- and long-range, pairing, complexity and chaotic dynamics)
- Development of Statistical Modeling of various nuclear properties using statistical analysis methods (neuronic networks etc)
Pythagoras Program – Artificial Intelligence Modeling
Main aims are: i) enrich knowledge of the structure and dynamics of nuclei (focusing on nuclei far from stability) and multi-nucleon systems ii) obtain reliable estimations of nuclear observables that are necessary for the understanding of several astrophysical phenomena and processes iii) develop theoretical-calculational techniques for the microscopic quantum theory of strongly-interacting particles, and the scattering theory due to time-dependent potentials, as well as the development of statistical machine learning methods.
