Research topics covered by this award include (i) development of new analytical and computational tools for the description of nuclear structure, especially for the nuclei far from stability; (ii) detailed consideration of specific new nuclear phenomena encountered with experimental advances into virgin territory of unstable nuclei; (iii) modeling of structural and dynamical aspects of nuclear processes of astrophysical interest; (iv) understanding nuclear matrix elements related to fundamental symmetries and double-beta decay and (v) development of the unified description of structure and reactions in open and marginally stable mesoscopic systems, including nuclear reactions, conductance fluctuations and quantum transport.We will train graduate students who are attracted to the activities in our group and to the number one ranked graduate school in nuclear physics in the US. 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? How do nuclear properties emerge from the underlying nucleon-nucleon interactions? How can we use nuclear data to understand fundamental symmetries and neutrino properties? 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).

该奖项涵盖的研究主题包括（i）开发新的分析和计算工具来描述核结构，特别是对于远离稳定的核； ㈡ 详细审议不稳定核处女地的实验进展所遇到的具体新核现象； (iii) 对具有天体物理学意义的核过程的结构和动力学方面进行建模； （iv）了解与基本对称性和双β衰变相关的核矩阵元素，以及（v）开发开放和边缘稳定介观系统中结构和反应的统一描述，包括核反应、电导涨落和量子输运。我们将训练被我们小组的活动以及美国排名第一的核物理研究生院所吸引的研究生。 我们提出的研究涉及广泛的科学问题，包括：核稳定性的极限是什么？宇宙的化学演化是如何进行的？核特性如何从潜在的核子-核子相互作用中显现出来？我们如何使用核数据来理解基本对称性和中微子特性？量子介观系统中秩序如何与混沌和复杂性共存？预计该计划将对核理论、核天体物理学和介观物理学一般领域的发展产生显着影响。许多项目都与国家超导回旋加速器实验室（NSCL）和其他实验室的实验项目相关。该项目还与核天体物理联合研究所（JINA）密切合作。
