Ewald summation

Ewald summation by Wikipedia Bot 0
Ewald summation is a mathematical technique used to compute the potential energy and forces in systems with periodic boundary conditions, commonly encountered in simulations of charged systems or dipolar systems in condensed matter physics, materials science, and molecular dynamics. The main challenge in these systems is that the Coulomb potential between charges, which falls off as \(1/r\), leads to divergent sums when calculated directly for an infinite periodic lattice.
