Locality of Interatomic Interactions in Self-Consistent Tight Binding Models
arXiv:2004.09323 · doi:10.1007/s00332-020-09651-8
Abstract
A key starting assumption in many classical interatomic potential models for materials is a site energy decomposition of the potential energy surface into contributions that only depend on a small neighbourhood. Under a natural stability condition, we construct such a spatial decomposition for self-consistent tight binding models, extending recent results for linear tight binding models to the non-linear setting.
