Ab initio calculations of the neutron skin and the electric dipole response of nuclei — •Sonia Bacca — TRIUMF, Vancouver, Canada

The nuclear dipole response and its sum-rules are strongly correlated with the size of atomic nuclei. They also informs us about the neutron equation of state and thus link atomic nuclei to neutron stars [1]. Combining the Lorentz integral transform with the coupled-cluster method allowed us to perform ab initio computations of response functions for medium mass nuclei [2,3]. I will show recent highlights in conjunction with calculations of neutron skins and discuss them in light of recent and future experiments [1,4]. [1] G.
