Nuclear Many-Body Theory
Welcome
A nucleus is a quantum many-body system consisting of two types of fermions, neutrons and protons, called nucleons, which are self-bound by a strong nuclear force. The number of constituent nucleons ranges from a few to a few hundred. Although the number is not very large, the nuclei exhibit various collective behaviors. Surprisingly, it is well established that the concept of single-particle motion in a mean field holds in nuclear structures despite the strong interaction between nucleons. The potential is collectively generated by all nucleons constituting the nucleus. The single-particle picture of the shell model, like electrons in an atom, emerges as a result of the collective effects of all nucleons generating the self-consistent mean field. In addition, some nuclei show a pattern of vibrational or rotational excitations as a whole, and some exhibit characteristic features of superfluids. We develop computational approaches based on quantum many-body theories to comprehensively delineate the intricate collective behaviors exhibited by nuclei. We welcome you to join us to explore the world of quantum nuclear systems.
