Title:     Weak properties of nuclei from first principles

Abstract: In this talk I will present recent highlights in computing
weak properties of nuclei using coupled-­‐cluster theory with
interactions and currents from chiral effective field theory. The
coupled-­‐cluster method is a microscopic theory that can
naturally account for (i) effects of three nucleon forces, (ii) the
presence of open decay channels and particle continuum, and (iii)
many-­‐nucleon correlations. All these ingredients are necessary
in order to build a framework with predictive capabilities applicable at
the extremes of the nuclear chart and with relevance for experimental
programs at rare isotope beam facilities. The topics I will discuss in
this talk include: (i) what are the microscopic origins of the quenching
of the axial vector coupling g_A? (ii) Revisiting the anomalous life
time of 14C, (iii) optimization of chiral NN and 3N interactions that
describe nuclear binding energies and radii accurately, (iv) the (weak)
charge distributions in 48Ca from first principles and other correlated
observables (such as the dipole polarizability) relevant to the Calcium
Radius Experiment (CREX) at Jefferson Laboratory.
