The 1D Hydrogen Solid

Solid hydrogen (3D) exists in different modifications. The low-pressure modification is a hexagonal lattice with a diatomic base, in particular a H2 molecule on each lattice side. In this modification the hydrogen solid is an insulator. Under high pressures solid hydrogen undergoes a phase-transition and becomes metallic. In this high-pressure modification the base of the lattice is mono-atomic.
