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.

Similarity-transformed chiral NN + 3N interactions for the ab initio description of 12C and 16O.
TL;DR: By introducing an adaptive importance truncation for the NCSM model space and an efficient JT-coupling scheme for the 3N matrix elements, this work is able to surpass previous N CSM studies including 3N interactions.

On the RMS radius of the proton
TL;DR: In this paper, the authors study the world data on elastic electron-proton scattering in order to determine the proton charge rms-radius after accounting for the Coulomb distortion and using a parameterization that allows to deal properly with the higher moments.

Spurious center-of-mass motion

TL;DR: In this article, a simple numerical procedure is given for the removal of states with spurious center-of-mass components, which does not require explicit construction of the spurious states and is shown that removal of spurious components signifivantly modifies the 16 O spectrum of Zuker, Buck and McGrory.
