The ground-state energies of rhombohedral and body-centred tetragonal atomic lattices in very strong magnetic fields have been calculated by means of density functionals. The exchange-correlation functional is that adopted in previous calculations of atomic and molecular chain ground-state energies. Approximate electronic eigenfunctions and eigenvalues of the lattice Kohn–Sham potential have been obtained by a local approximation in one angular variable. As a consequence, the implementation of density functional theory is less rigorous than in the previously published work on atoms and linear molecular chains. Atomic cohesive energies and electron chemical potentials have been derived for atomic numbers and magnetic flux densities relevant to the stellar surface in radio pulsars. The cohesive energies are small and, though subject to errors caused by the local approximation, show unambiguously that the electric field boundary condition is E·B=0 at the surface.
