An efficient and fast prediction of positions and dynamics of particles is of great importance in order to reduce computational efforts. This thesis focuses on extending the existing SE(3)-transformer-based graph neural network (GNN) approach proposed by Fuchs et al.[1], which successfully employs a self-attention mechanism for point clouds to describe dynamics of charged particles. The exten- sion developed in our study is aimed to improve an accuracy of molecular dynamics prediction for a more complex system consisting of particles with an orientation- dependent interaction and rotational degrees of freedom. As an example, a physical model presented as a fluid of charged particles bearing electric dipoles is examined. It is shown that our approach, which introduces a new attention mechanism, pro- vides better accuracy in describing such systems compared to the original approach. popup.nrat_date 2025-11-05 Close
