Abstract:Â Although quantum chromodynamics (QCD) has long been accepted as the underlying theory of the strong nuclear force, connecting the structure and interactions of nuclei to the fundamental parameters of QCD remains challenging. I will discuss new methods arising from re-interpreting lattice QCD spectroscopy in terms of the Lanczos algorithm for quantifying challenging systematic uncertainties associated with excited-state effects that have bedeviled lattice QCD calculations of two-nucleon systems for over a decade. I will also present nonrelativistic effective field theory results that can shed light on a simpler version of the problem: when all quark masses are much heavier than the confinement scale, do nucleons form nuclear bound states analogous to molecular bound states of atoms?
