Recent ab initio lattice studies have found that the interactions between alpha particles (^{4}He nuclei) are sensitive to seemingly minor details of the nucleon-nucleon force, such as interaction locality. In order to uncover the essential physics of this puzzling phenomenon without unnecessary complications, we study a simple model involving two-component fermions in one spatial dimension. We probe the interaction between two bound dimers for several different particle-particle interactions… Expand

Essential elements for nuclear binding
How does nuclear binding emerge from first principles? Our current best understanding of nuclear forces is based on a systematic low-energy expansion called chiral effective field theory. However,Expand

The introduction of chiral effective field theory by Steven Weinberg three decades ago has had a profound and lasting impact on nuclear physics. This brief review explores the impact of Weinberg’sExpand
Effective interactions between nuclear clusters
The effective interactions between two nuclear clusters, $d+d, t+t$, and $\ensuremath{\alpha}+\ensuremath{\alpha}$, are investigated within a cluster model using local nucleon-nucleon ($NN$) forces.Expand
Ab Initio Nuclear Thermodynamics.
A new Monte Carlo method called the pinhole trace algorithm for ab-initio calculations of the thermodynamics of nuclear systems is proposed and the first ab initio study of the density and temperature dependence of nuclear clustering is presented. Expand
