happy to have played a (very small) part in this paper: arxiv.org/abs/2610.00794, studying some of the pitfalls and difficulties of training long-range models to represent actual electrostatics. go have a read!

Long-Range Machine Learning Interatomic Potentials for Defect Energetics in SrTiO$_3$
Machine learning interatomic potentials (MLIPs) have advanced rapidly in recent years, yet the majority of models remain semilocal in nature and neglect long-range electrostatic interactions. A growin...
