-  * Better interactions/​density functionals/​Hamiltonians,​ and improved many-body techniques across the nuclear chart. In particular, improvements in the behavior for neutron matter and neutron-rich nuclei. We need precision masses of medium and heavy neutron-rich nuclei.+  ​* **Better interactions/​density functionals/​Hamiltonians,​ and improved many-body techniques across the nuclear chart.

-  * A clear delineation of the systematic uncertainties associated with the relationship between nuclear matter and the structure of nuclei. What is the uncertainty due to using the wrong interaction/​density functional/​hamiltonian,​ and what is the uncertainty due to the many-body technique (shell model, HFB, RPA, etc.)? We need to know L and S at the few percent level.+  ​* **A clear delineation of the systematic uncertainties associated with the relationship between nuclear matter and the structure of nuclei.

-  * Understanding the limits of chiral effective theory: how high can we go in density for both neutron and nuclear matter? What is the systematic uncertainty associated with the cutoffs? How far can quantum Monte Carlo go? Why are the three-nucleon interactions from these two approaches so different?+  ​* **Understanding the limits of chiral effective theory: how high can we go in density for both neutron and nuclear matter?

   * A clear delination of the nuclear physics input needed for core-collapse supernovae simulations:​ EOS, neutrino opacities, electron capture rates, etc. How does the progenitor determine the neutron star mass, spin, and magnetic field? Can we accurately predict the proto-neutron star neutrino signal?   * A clear delination of the nuclear physics input needed for core-collapse supernovae simulations:​ EOS, neutrino opacities, electron capture rates, etc. How does the progenitor determine the neutron star mass, spin, and magnetic field?
