Abstract

The main focus of the present thematic proposal is contemplating theoretical investigations on dynamics related to ultra-cold atoms and weakly-bound nuclear and atomic physics close to zero temperatures, which are associated with the corresponding phenomenology that is being intensively studied in the last decades in hundred laboratories around the world. In this regard, our theoretical proposals are in line with such experimental activities. Concerned with cold-atom physics, the studies of our theoretical group in São Paulo are part of the international effort to go deep in the fundamental aspects of quantum theories, in view of possible future applications. In this regard, we see as the main target a better understanding of all dynamics associated with the atomic Bose-Einstein condensation, as well as ultra-cold Bose-Fermi mixtures, having the main targets possible applications in superfluidity, superconductivity and quantum computers, among other new quantum technologies relying in the understanding of fundamental quantum aspects.With respect to nuclear, hadronic physics and Theoretical Field Theory, the main interest in the actualtheoretical investigations are on understanding fundamental hadronic interactions, together with nuclear physics aspects related to weakly-bound and radioactive nuclei, with excess of neutrons or protons, in particular by considering nuclear reactions of light weakly-bound nuclei against heavy nuclei. These researchers are expected to be relevant not only in understanding the fundamental structure of nuclei, but also considering their role in astrophysics. (AU)
