  We derived microscopic optical potentials (OPs) for elastic nucleon-nucleus
scattering within the framework of chiral effective field theories at the
first-order term of the spectator expansion of the Watson multiple-scattering
theory and adopting the impulse approximation. Our OPs are derived by folding
ab initio nuclear densities with a nucleon-nucleon NN t matrix computed with a
consistent chiral interaction. The results of our OPs are in good agreement
with the experimental data. Recent achievements of our work are reviewed in
this contribution.
