Nuclear Structure, Nuclear Astrophysics and Mesoscopic Physics

我们提议的研究涉及广泛的科学问题，包括：核稳定的极限是什么？宇宙的化学进化是如何进行的？多体系统相互作用的自组织方式有哪些？核子-核子相互作用下的核性质是如何产生的？在量子介观系统中，有序如何与混沌和复杂性共存？预计该计划将对核理论、核天体物理和介观物理的一般领域的发展产生重大影响。许多项目与国家超导回旋实验室(NSCL)和其他实验室的实验计划有关。研究课题包括：(1)开发描述核结构的新的分析和计算工具，特别是描述远离稳定的核和重核的核结构；(2)详细审议特定的核现象和核过程，阐明在不稳定核的初始领域取得的实验进展所遇到的新特征；(3)对具有天体物理意义的核过程的结构和动力学方面进行计算和建模；(4)开发开放和边缘稳定的介观系统的结构和反应的统一描述，包括核反应、电导波动和量子输运；(4)核作为介观系统的研究，包括多体量子混沌及其集体和规则特征的共存。

Our proposed research relates to broad questions in science including: What are the limits of nuclear stability? How did the chemical evolution of the Universe proceed? What are the ways of self-organization in interacting many-body systems? How do the nuclear properties emerge from the underlying nucleon-nucleon interactions? How does order coexist with chaos and complexity in quantum mesoscopic systems? The suggested program is expected to have appreciable impact on developments in the field of nuclear theory, nuclear astrophysics and the general field of mesoscopic physics. Many of the projects are connected to the experimental programs at the National Superconducting Cyclotron Laboratory (NSCL) and other laboratories. Projects are also closely coupled with the Joint Institute for Nuclear Astrophysics (JINA).Research topics include: (i) development of new analytical and computational tools for the description of nuclear structure, especially for the nuclei far from stability and for heavy nuclei; (ii) detailed consideration of specific nuclear phenomena and nuclear processes that shed light on the new features encountered with experimental advances into virgin territory of unstable nuclei; (iii) calculations and modeling of structural and dynamical aspects of nuclear processes of astrophysical interest; (iv) development of the unified description of structure and reactions in open and marginally stable mesoscopic systems, including nuclear reactions, conductance fluctuations and quantum transport; (iv) studies of the nucleus as a mesoscopic system, including many-body quantum chaos and its coexistence with collective and regular features.
