This research program focuses on strongly interacting systems appearing in laboratories on earth and in astrophysical settings. Specifically, I 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). My 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 the underlying level (of quarks and gluons), b) exotic states that emerge when many particles come together, e.g., superfluidity, the absence of viscous flow, c) the cross-pollination between different areas of physics, i.e., the use of ultracold atomic gases or other systems 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.

这项研究计划专注于出现在地球实验室和天体物理环境中的强相互作用系统。具体地说，我在理论上研究中子星(致密的天体物理物体)、原子核(特别是在最先进的实验设备中创造的同位素)和冷原子(地球上最冷的系统)。我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，b)当许多粒子聚集在一起时出现的奇异状态，例如超流，没有粘性流动，c)不同物理领域之间的交叉授粉，即使用超冷原子气体或其他系统来提供对中子和质子性质的实验限制。研究生和本科生(包括暑期学生)在这些研究中起着主要作用。
