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 analyzing 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 the
interesting applications, including the studies
of reflection asymmetric (or pear-shaped)
nuclei and nuclei with odd number of
nucleons, which are hot topics in nuclear
structure research in recent years.
