Multilayer atomic cluster expansion for semilocal interactions

Blog Article

Traditionally, interatomic potentials assume local bond formation supplemented by long-range electrostatic interactions when necessary.This ignores intermediate-range multiatom interactions that arise from the 3 nef runes relaxation of the electronic structure.Here, we present the multilayer atomic cluster expansion (ml-ACE) that includes collective, semi-local multiatom interactions naturally within its remit.

We demonstrate that ml-ACE significantly improves fit accuracy and efficiency compared to a local expansion on selected examples j??kaapin raikastin and provide physical intuition to understand this improvement.
