First-principles investigations of neutron and nuclear matter are at the forefront of research activities in nuclear physics and take ample advantage of the recent advances in high-performance computing. This project will lay the groundwork for finite-temperature studies of nuclear physics by pursuing the systematic study of strongly-coupled Fermi systems and by testing this approach with related few- and many-body problems in atomic physics. The numerical methods developed here focus on nonperturbative aspects of the nuclear many-body problem and the results are expected to impact other fields such as atomic and condensed matter physics, high-energy physics and astrophysics. The group will establish a database of Monte Carlo configurations that will serve the scientific community in the USA and abroad.This project will promote an interdisciplinary study employing advanced first-principles calculations in several fields, ranging from nuclear physics to condensed matter and atomic physics. This will present unique opportunities for undergraduate and graduate students to develop a broad understanding of various physical systems and perform creative multidisciplinary research. The database developed here will provide hands-on tools useful for teaching nonperturbative numerical methods for students worldwide. Education at the undergraduate level will benefit the local Computational Astronomy and Physics Research Experience for Undergraduates (CAP-REU) program.

中子和核物质的第一性原理研究处于核物理研究活动的最前沿，充分利用了高性能计算的最新进展。该项目将通过对强耦合费米系统的系统研究，并通过用原子物理学中相关的少体和多体问题测试这一方法，为核物理学的有限温度研究奠定基础。这里开发的数值方法专注于核多体问题的非微扰方面，其结果预计将影响其他领域，如原子和凝聚态物理，高能物理和天体物理。该研究小组将建立一个服务于美国和国外科学界的蒙特卡罗组态数据库。该项目将促进从核物理到凝聚态和原子物理等多个领域的跨学科研究，采用先进的第一性原理计算。这将为本科生和研究生提供独特的机会，以发展对各种物理系统的广泛理解，并进行创造性的多学科研究。这里开发的数据库将为世界各地的学生提供实用的非微扰数值方法教学工具。在本科层次的教育将有利于当地的计算天文学和物理研究经验的本科生（CAP-REU）计划。
