Particle mesh Ewald: An N⋅log (N) method for Ewald sums in large ...
Webb15 nov. 1995 · The previously developed particle mesh Ewald method is reformulated in terms of efficient B‐spline interpolation of the structure factors. This reformulation allows a natural extension of the method to potentials of the form 1/rp with p≥1. Furthermore, efficient calculation of the virial tensor follows. 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 easter decorations for yard
