Atomic nuclei are strongly interacting, quantum many-body systems displaying fascinating properties: they exhibit emergent phenomena characteristic of large complex systems while at the same time being laboratories of most fundamental laws of nature. Using advanced applied mathematics, computer science, and physics, the project objective is to accurately describe the atomic nucleus in its entirety. To this end, the research team treats a wide range of nuclei, studying their electroweak transitions and reactions as these are important in both terrestrial experiments and astrophysical environments and will enable predictions for basic science and for applications in nuclear energy, nuclear security, and nuclear astrophysics.
