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.

Ab initio symplectic no-core shell model
TL;DR: In this paper, a translationally invariant symplectic configuration in the spherical harmonic oscillator basis is given, which is used to reveal the extent to which symplectic configurations enter into low-lying states in 12C and 16O nuclei calculated within the framework of the NCSM with the JISP16 realistic nucleon?nucleon interaction.

Benchmarks of the full configuration interaction, Monte Carlo shell model, and no-core full configuration methods
TL;DR: In this paper, the authors report no-core solutions for properties of light nuclei with three different approaches in order to assess the accuracy and convergence rates of each method, including full configuration interaction (FCI), Monte Carlo shell model (MCSM), and no core full configuration (NCFC) approaches.

Nucleon–Nucleon Interaction in the J-Matrix Inverse Scattering Approach and Few-Nucleon Systems
TL;DR: In this paper, the nucleon-nucleon interaction is constructed by means of the J-matrix version of inverse scattering theory, which is used in the no-core shell model calculations of 3H and 4He nuclei.
