Guesstimation of Molecular Ensemble Electrostatics Properties Through SCERPA‐DFT Calculation: Molecular Field‐Coupled Nanocomputing as a Case Study

Advanced Theory and Simulations, Volume 8, Issue 10, October 2025.
This work presents a framework combining the Self‐Consistent Electrostatic Potential Algorithm (SCERPA) and Density‐Functional Theory calculations to efficiently evaluate the electronic properties of molecular ensembles. The approach achieves ab initio‐comparable precision while significantly reducing computation time and provides the first DFT ...
