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.

Nuclear binding energies from moment methods: Realistic effective no-core Hamiltonian
F. J. Margetan,J. P. Vary +1 more
TL;DR: In this paper, the lowest few moments of H/sub eff/ were evaluated in an oscillator model space of four major shells and these moments were then used to determine a number of continuous and discrete density of states functions, each of which yields an estimate for the ground state energy.

Thermal properties of {sup 40}Ca and {sup 90}Zr
Mahmoud A. Hasan,James P. Vary +1 more
TL;DR: In this paper, the thermal properties of Ca and Zr with two different effective Hamiltonians in a mean-field approach were evaluated and observed differences in the results were traced to the dependence of thermal properties on the shell gap near the Fermi surface which varies with the choice of Hamiltonian.

Minimizing effective many-body interactions
TL;DR: In this paper, a simple two-level model is developed and used to test the properties of effective interactions for performing nuclear structure calculations in truncated model spaces, and it is shown that the effective many-body interactions sensitively depend on the choice of the single-particle basis and they appear to be minimized when a self-consistent Hartree-Fock basis is used.

Effective interaction calculations: Where do we go from here?
TL;DR: In this paper, the authors discuss some new approaches for calculating the effective shell-model interaction and present a simple but useful form for the effective interaction (a la Kuo and Brown).
