Nuclear Structure Theory and its Applications

本提案围绕核结构理论及其在天体物理、粒子物理和凝聚态物理中的应用展开。其中一个主要主题是发展适当的理论工具来描述远离稳定的原子核，并将其应用于各种预期的新现象。提出了富中子核的变形晕、N = Z核的质子-中子对关联、核子转移反应的新特征、核有效相互作用和衰变率等方面的研究。其他核结构项目涉及质子-中子单极力和单粒子共振在将核的高自旋结构延伸到带终止点以外的可能作用。该提案的第二个主题是将映射技术应用于核结构领域以外的问题。重子映射，最近被证明是一种有希望的直接从组成夸克构建原子核的方法，将应用于一核子和二核子系统以及对称核物质。玻色子映射将用于处理反铁磁自旋链的动力学，作为早期工作的延伸。

This proposal centers around nuclear structure theory and its applications in astrophysics, particle physics and condensed matter physics. One of the principal themes is the development of appropriate theoretical tools for the description of nuclei far from stability and their application to the variety of new phenomena expected. Studies related to deformed halos in neutron-rich nuclei, to proton-neutron pairing correlations in N = Z nuclei, and to new features of nucleon transfer reactions, the nuclear effective interaction and beta decay rates are proposed. Other nuclear structure projects are concerned with the proton-neutron monopole force and the possible role of single-particle resonances in extending the high spin structure of nuclei beyond the band termination point.A secondary theme of the proposal concerns the application of mapping techniques to problems outside the nuclear structure domain. Baryon mappings, which have recently been shown to be promising as a means of building nuclei directly from constituent quarks, will be applied to one- and two-nucleon systems and to symmetric nuclear matter. Boson mappings will be used to treat the dynamics of antiferromagnetic spin chains, in an extension of earlier work.
