Neutron matter is interesting both as an extension of terrestrial nuclear
physics and due to its significance for the study of neutron stars. In this
work, after some introductory comments on nuclear forces, nuclear ab initio
theory, and nuclear phenomenology, we employ two techniques, Quantum Monte
Carlo (QMC) and Density Functional Theory, to practically handle an extended
system composed of strongly interacting neutrons. We start by summarizing work
on the static response of neutron matter, which considers the impact of
external influences on the time-independent system. We then proceed to discuss
new results of the energy of quasiparticle excitations in neutron matter,
including QMC calculations with chiral or phenomenological nucleon-nucleon
interactions. As part of this study, we carefully study the approach of our
finite-number computations toward the infinite-system limit.
