Research in Theoretical Nuclear Physics

拟议的研究计划是在理论物理领域，重点是太阳和超新星中微子；库仑势垒以下的聚变反应；元素的起源，特别是r过程核合成；以及中微子天体物理的其他方面。选择这些领域的理论研究是为了与美国和国外正在进行的实验计划密切结合。拟议工作的智力价值：成功完成拟议的项目将有助于：1)更好地了解中微子质量和混合物；2)了解中微子在包括致密中微子气体在内的致密介质中的传播；3)更好地理解核心塌缩超新星的各个方面；4)更好地了解元素的来源，特别是在快速中子捕获中产生的元素；5)更好地了解天体物理环境中的聚变；以及6)探索稀土离子加速器用于中微子物理的潜力。拟议活动产生更广泛的影响：拟议的研究有助于支持核科学方面的国家优先事项，如拟议的深层地下科学实验室和稀有离子加速器。除了加强国家在地下科学和核物理方面的研究和教育基础设施外，这些拟议的设施还将进行重大的外联工作。这项拟议的研究涉及威斯康星大学麦迪逊分校和加州大学圣地亚哥分校之间的合作，以及威斯康星大学麦迪逊分校研究人员与来自巴西、法国、日本和土耳其的研究人员之间的国际合作。主要研究人员参与了将粒子、核物理、凝聚态物理和天体物理联系起来的多学科研究活动。他和其他团队成员也参与了向更广泛的受众展示物理学的工作。

The proposed program of research is in the area of theoretical physics with an emphasis on solar and supernova neutrinos; fusion reactions below the Coulomb barrier; the origin of elements, in particular r-process nucleosynthesis; and other aspects of neutrino astrophysics. Theoretical research in these areas is chosen to have a close coupling with the ongoing experimental programs in the United States and abroad. Intellectual Merit of the Proposed Work: Successful completion of the proposed projects will lead to i) A better understanding of neutrino masses and mixings; ii) Understanding neutrino propagation through dense media including dense neutrino gases; iii) A better understanding of various aspects of core-collapse supernovae; iv) A better understanding of the origin of elements, especially those produced in rapid neutron capture; v) A better understanding of fusion in astrophysical environments; and vi) Exploring the potential of rare-ion accelerators for neutrino physics. Broader Impacts Resulting from the Proposed Activity: Proposed research contributes to the support of national priorities in nuclear science such as the proposed Deep Underground Science Laboratory and Rare Ion Accelerator. In addition to enhancing research and education infrastructure of the Nation in underground science and nuclear physics, these proposed facilities will have significant outreach efforts. The proposed research involves collaboration between University of Wisconsin-Madison and University of California at San Diego, as well as international collaborations between University of Wisconsin-Madison researchers and those from Brazil, France, Japan, and Turkey.The principal investigator participates in multidisciplinary research activities that connect particle, nuclear, condensed-matter physics and astrophysics. He and other team members are also involved in exposing physics to broader audiences.
