Although the method has inferior asymptotic computational complexity to its linear scaling competitors, it remains enormously popular due to its high efficiency, which stems from the use of fast Fourier transforms (FFTs). Ewald summation was developed as a method in theoretical physics, long before the advent of computers. However, the Ewald method has enjoyed widespread use since the 1970s in computer simulations of particle systems, especially those whose particles interact via an inverse square force law such as gravity or … Visa mer Ewald summation, named after Paul Peter Ewald, is a method for computing long-range interactions (e.g. electrostatic interactions) in periodic systems. It was first developed as the method for calculating … Visa mer The electrostatic energy of a polar crystal (i.e. a crystal with a net dipole $${\displaystyle \mathbf {p} _{uc}}$$ in the unit cell) is conditionally convergent, i.e. depends on the order of the summation. For example, if the dipole-dipole interactions of a … Visa mer • Paul Peter Ewald • Madelung constant • Poisson summation formula • Molecular modeling Visa mer Ewald summation rewrites the interaction potential as the sum of two terms, $${\displaystyle \varphi (\mathbf {r} )\ {\stackrel {\mathrm {def} }{=}}\ \varphi _{sr}(\mathbf {r} )+\varphi _{\ell r}(\mathbf {r} )}$$, where Visa mer The Ewald summation was developed by Paul Peter Ewald in 1921 (see References below) to determine the electrostatic energy (and, hence, the Madelung constant) of ionic crystals. Visa mer Generally, different Ewald summation methods give different time complexities. Direct calculation gives $${\displaystyle O(N^{2})}$$, where $${\displaystyle N}$$ is the number of atoms in the system. The PME method gives $${\displaystyle O(N\,\log N)}$$ Visa mer find the vertex formula
