Comments on “Ewald summation technique for one-dimensional charge distributions” Original Research Article

The article entitled “Ewald summation technique for one-dimensional charge distributions” by Langridge, Hart, and Crampin (Comput. Phys. Commun. 134 (2001) 78) introduces a technique for accelerating convergence of the lattice sums describing long-range electrostatic interactions in these systems. Unfortunately, because the work does not include connections to earlier relevant contributions, it does not address known computational problems associated with the proposed technique. These problems are reviewed and satisfactory methods for overcoming them are identified.
