Strongly interacting nucleons

本研究项目涉及在地球实验室和天体物理环境中出现的强相互作用系统。具体来说，我们在理论上研究中子星（紧凑的天体物理对象），原子核（特别是在最先进的实验设施中产生的同位素）和冷原子（地球上最冷的系统）。我们的研究范围从纸笔直观的方法到现代超级计算机上的大规模计算。解决的具体问题包括：a)试图将中子和质子之间的相互作用与底层（夸克和胶子）联系起来，另一方面，对大型核系统的研究；b)原子核和恒星中超流动性的物理学（即缺乏粘性流动）；c)使用超冷原子气体系统来提供中子和质子性质的实验约束。研究生和本科生（包括暑期生）在这些研究中起主要作用

This research program addresses strongly interacting systems appearing in laboratories on earth and in astrophysical settings. Specifically, we theoretically investigate neutron stars (compact astrophysical objects), nuclei (especially the isotopes created in state-of-the-art experimental facilities), and cold atoms (the coldest systems on earth). Our studies range from pen-and-paper intuitive approaches to large-scale calculations on modern supercomputers. Specific problems tackled include: a) the attempt to connect the interactions between neutrons and protons to, on the one hand, the underlying level (of quarks and gluons) and, on the other, studies of large nuclear systems, b) the physics of superfluidity (i.e., the absence of viscous flow) in nuclei and in stars, c) the use of systems of ultracold atomic gases to provide experimental constraints on the properties of neutrons and protons. Graduate and undergraduate students (including summer students) play a major role in these studies.**
