In order to investigate many-body dynamics in nuclear excitations and reactions, we have developed a number of new theoretical/computational methodologies based on the (time-dependent) density functional theory; especially in the linear response calculation, the real-time calculation, and the large amplitude collective motion theory. We also improved the pairing energy functional for more reliable predictions. Utilizing these new techniques, we have performed systematic numerical analysis for stable and unstable nuclei, to study properties of exotic elementary modes of excitation in unstable nuclei with unbalanced numbers of neutron sand protons.
