Modern Ab Initio Approaches and Applications in Few-Nucleon Physics with A \ge 4
We present an overview of the evolution of ab initio methods for few-nucleon
systems with A \ge 4, tracing the progress made that today allows precision
calculations for these systems. First a succinct description of the diverse
approaches is given. In order to identify analogies and differences the methods
are grouped according to different formulations of the quantum mechanical
many-body problem. Various significant applications from the past and present
are described. We discuss the results with emphasis on the developments
following the original implementations of the approaches. In particular we
highlight benchmark results which represent important milestones towards
setting an ever growing standard for theoretical calculations. This is relevant
for meaningful comparisons with experimental data. Such comparisons may reveal
whether a specific force model is appropriate for the description of nuclear
dynamics.Comment: extension of the previous version from 70 to 78 pages, 24 figures, 17
