Query: Neutron Star Crust and Molecular Dynamics Simulation   In this book chapter we review plasma crystals in the laboratory, in the
interior of white dwarf stars, and in the crust of neutron stars. We describe a
molecular dynamics formalism and show results for many neutron star crust
properties including phase separation upon freezing, diffusion, breaking
strain, shear viscosity and dynamics response of nuclear pasta. We end with a
summary and discuss open questions and challenges for the future.
