----SEMINAR ABSTRACT--------------------------------------------------
Like other finite quantum many-body systems, atomic nucleus exhibits stunning collective excitations that are associated with geometrical shapes. The growing interest in the study of nuclear shapes and collective excitations, including those of short-lived nuclei that are becoming accessible in experiments at radioactive-ion-beam facilities worldwide, necessitates a timely systematic theoretical analysis. On the other hand, the underlying nucleonic dynamics is highly complex that a quantitative, as well as reliable, description of these phenomena presents a major theoretical challenge.
This talk will focus on the recently developed method that is constructed by bridging the microscopic framework provided by the nuclear density functional theory and algebraic theory of interacting bosons. The method has opened up many new possibilities of analysing complex nuclear shapes and collective excitations in an accurate, systematic and computationally feasible manner. I will present the basic notions of the method and highlight recent applications to the topics that include the phenomena of quantum phase transitions and shape coexistence, and the spectroscopy of nuclei with odd number of nucleons. These are recurrent themes of interest in low-energy nuclear physics.
