Description
Recent advances in high-precision experimental techniques, such as the QUARTET collaboration with muonic atom spectroscopy, are pushing the boundaries of our ability to measure the absolute charge radii and structural properties of light nuclei. However, extracting fundamental physics from these high-precision measurements requires equally precise, first-principles theoretical inputs. Here, I will discuss our work utilizing the ab initio No-Core Shell Model with Continuum (NCSMC), which provides an unified approach to describe both nuclear structure and reactions, to meet this need and more specifically to calculate nuclear charge and magnetic densities. These inputs can also be used for the pipeline that we are developing from nuclear to atomic ab initio QED calculation, namely Multi-Configuration Dirac-Fock method, to solve for muonic hyperfine splitting.
