ICN2 Seminar: Fast electron density estimation of molecules, liquids, and solids using neural networks
Date: February 2023

Abstract: In this talk I will present DeepDFT, a machine learning framework for the prediction of the electron density. I will give a brief introduction to deep learning for physics, leading into recent work on graph neural networks on which the model is based upon. The model is tested on multiple datasets of molecules (QM9), liquid ethylene carbonate electrolyte and lithium ion battery cathode material (NMC). The accuracy on all three datasets is beyond state of the art and the computation time is orders of magnitude faster than DFT.
