Astrophysics & reactions of light nuclei, and some quantum Monte Carlo

Toward ab initio calculations of astrophysical reaction rates

There has been tremendous progress in recent years in the description of nuclei as collections of interacting nucleons: the low-lying energy spectra of many light nuclei have been successfully computed from the vacuum nucleon-nucleon interaction and an additional three-nucleon interaction. These ab initio calculations have mostly focused on static properties of nuclei, particularly the energies...

Data on low-energy hadron production in collisions of nucleons, pions and kaons with light nuclei are needed for many astrophysical and accelerator applications. Modern simulations have reached a level of accuracy that the lack of detailed understanding of hadron production processes has become one of the most important limitations to further improvements. After giving some examples of hadropro...

Few-body reference data for multicomponent formalisms: Light-nuclei molecules

We present full quantum statistical energetics of some electron–light-nuclei systems. This is accomplished with the path-integral Monte Carlo method. The effects on energetics arising from the change in the nuclear mass are studied. The obtained results may serve as reference data for the multicomponent density functional theory calculations of light-nuclei systems. In addition, the results rep...

Quantum Monte Carlo Calculations of Light Nuclei

The goal of ab-initio light-nuclei calculations is to understand nuclei as collections of nucleons interacting with realistic (bare) potentials through reliable solutions of the many-nucleon Schrödinger equation. Such calculations can study binding energies, excitation spectra, relative stability, densities, transition amplitudes, cluster-cluster overlaps, low-energy astrophysical reactions, an...
