Structured force reformulation of many-body dispersion: towards effective atom--atom decomposition and surrogate modeling
Zhaoxiang Shen, Raúl I. Sosa, Stéphane P. A. Bordas +2
We present a structured force reformulation of the many-body dispersion (MBD) model that enables a physically consistent decomposition of forces into pairwise components. By introd…

Machine learning surrogate models of many-body dispersion interactions in polymer melts
Zhaoxiang Shen, Raúl I. Sosa, Jakub Lengiewicz +2
Accurate prediction of many-body dispersion (MBD) interactions is essential for understanding the van der Waals forces that govern the behavior of many complex molecular systems. H…

Quantum-informed simulations for mechanics of materials: DFTB+MBD framework
Zhaoxiang Shen, Raúl I. Sosa, Stéphane P. A. Bordas +2
The macroscopic behaviors of materials are determined by interactions that occur at multiple lengths and time scales. Depending on the application, describing, predicting, and unde…
