Query: Coupled-cluster computations of optical potential for medium-mass nuclei   Recent progress in the numerical solution of the nuclear many-body problem
and in the development of nuclear Hamiltonians rooted in Quantum
Chromodynamics, has opened the door to first-principle computations of nuclear
reactions. In this article, we discuss the current status of ab initio
calculations of nucleon-nucleus optical potentials for medium-mass systems,
with a focus on results obtained with the coupled-cluster method.
