Microscopic simulations of strongly correlated systems, such as neutron matter (NM), is restricted to a small number of particles due to various complexities. Thus, to understand the physics of infinite systems one has to consider the finite size effects (FSE) arising from these limitations on system size. These conference proceedings are centered around different ways of treating FSE in order to study NM. Specifically, we first present a preliminary study, at the mean field level and beyond, of FSE in the pairing gap of neutron superfluids. We also present a systematic model-independent extraction of the effective mass at various densities in NM using Quantum Monte Carlo (QMC) techniques.
