Abstract The ground‐state energies of hydrogenic and helium chains in superstrong magnetic fields (B ≈ 10 7 −10 9 Tesla) have been calculated within the single‐particle scheme of a heuristic density functional method. Applying the local density approximation ( LDA ), the simple Dirac exchange functional was used neglecting correlation effects. The equations were solved iteratively using a basis set of Landau functions in the transverse directions and directly integrating along the longitudinal direction. We obtained binding lengths and, by comparing the binding energies of the chains with the ground‐state energies of single atoms, we found condensation energies. © 1995 John Wiley & Sons, Inc.
