Description
I will discuss recent developments for constructing translationally invariant nonlocal optical potentials rooted in first principles and applicable to spherical and deformed targets up through the Ca region. First studies are now available for proton/neutron and deuteron projectiles at low energies and for light-mass targets. These applications build upon the merging of two successful approaches, namely, the Green's function technique and the ab initio symmetry-adapted no-core shell model that has expanded the reach of practically exact methods to medium-mass open-shell nuclei. I will also discuss uncertainty quantification for reaction observables that includes not only uncertainties that stem from the many-body approach but also from the underlying chiral parameterization. As an interesting application to quantum computing, we use these inter-cluster potentials to study the efficacy of various types of qubit mapping and provide first quantum simulations for Carbon isotopes.
