We explore the impact of optimizations of the single-particle basis on the convergence
behavior and robustness of ab initio no-core shell model calculations of nuclei. Our focus is …

We present an overview of recent results and developments of the no-core shell model
(NCSM), an ab initio approach to the nuclear many-body problem for light nuclei. In this …

Ab initio no-core configuration interaction (NCCI) calculations for the nuclear many-body
problem have traditionally relied upon an antisymmetrized product (Slater determinant) …

For light nuclei, ab initio many-body methods such as the no-core shell model are the tools
of choice for predictive, high-precision nuclear structure calculations. The applicability and …

We introduce a hybrid many-body approach that combines the flexibility of the No-Core
Shell Model (NCSM) with the efficiency of Multi-Configurational Perturbation Theory (MCPT) …

The applicability of nuclear ab initio calculations has rapidly extended over the past
decades. However, starting research projects is still challenging due to the required …

We present a qualitative improvement of the ab initio no-core shell model (NCSM) approach
by implementing three-body interaction capability for p-shell nuclei. We report the first …

The ab initio no-core shell model (NCSM) is extended to include a realistic three-body
interaction in calculations for p-shell nuclei. The NCSM formalism is reviewed and new …

We present a systematic study of the C 10–14 isotopes within the ab initio no-core shell-
model theory. We apply four different realistic nucleon-nucleon (NN) interactions:(i) the …

The spherical Hartree-Fock approximation is applied to the ab initio no-core shell model,
with a realistic effective nucleon-nucleon interaction in order to investigate the range of its …
