Simulation and understanding of atomic and molecular quantum crystals

This is the authors' abstract. We don't add key points for this paper.

Solids formed by light atoms or molecules have, at experimentally realizable low temperatures, a kinetic energy per particle that is large compared to the thermal energy. Examples include solid helium, hydrogen, and methane, which are important in a variety of contexts. This review provides an introduction to these quantum crystals, with a focus on simulation techniques suitable for describing and understanding them.
