Ab initio no core shell model
TLDR
In this paper, a non-perturbative ab initio no core shell model (NCSM) was proposed to solve the properties of nuclei exactly for arbitrary nucleon-nucleon (N N ) and N N + ǫ − three-N n interactions with exact preservation of all symmetries.About:

Status and future of nuclear matrix elements for neutrinoless double-beta decay: a review.
TL;DR: The nuclear matrix elements that govern the rate of neutrinoless double beta decay must be accurately calculated if experiments are to reach their full potential as mentioned in this paper, which has been a long-studied problem.

Properties of 12C in the Ab initio nuclear shell model.
TL;DR: In this article, the binding energies, excitation spectra, and electromagnetic properties of the ab initio no-core nuclear shell model were derived microscopically from the realistic CD Bonn and the Argonne V8' nucleon-nucleon (NN) potentials as a function of the finite harmonic oscillator basis space.

The Configuration Interaction Method: Advances in Highly Correlated Approaches
TL;DR: In this article, the authors review the fundamentals of the configuration interaction method and discuss various determinant-based CI algorithms, and consider some applications of highly correlated CI methods, such as potential energy surfaces, describing electronic excited states and yield benchmark energies and molecular properties for use in calibrating more approximate methods.

Few-nucleon forces from chiral Lagrangians.
TL;DR: In this paper, a few-nucleon forces were considered from the point of view of effective chiral Lagrangians, and it was argued that such forces naturally arise at the same order in chiral perturbation theory as some important features of the two-Nucleon force.
