Analytic Boundary Terms for Arbitrary Crystal Geometries and Direct-Sum Evaluation of Madelung Constants in Triclinic Lattices
Yang He, Zhonghan Hu
The direct-sum evaluation of Madelung constants is complicated by the conditional convergence of lattice sums, which gives rise to a shape-dependent boundary term. In this work, we…

The Madelung Problem of Finite Crystals
Yihao Zhao, Yang He, Zhonghan Hu
The Coulomb potential at an interior ion in a finite crystal of size is given by a linear superposition of contributions from displacement vectors to its…
