Transition1x -- a Dataset for Building Generalizable Reactive Machine Learning Potentials

no code implementations25 Jul 2022 Mathias Schreiner, Arghya Bhowmik, Tejs Vegge, Jonas Busk, Ole Winther

In this work, we present the dataset Transition1x containing 9. 6 million Density Functional Theory (DFT) calculations of forces and energies of molecular configurations on and around reaction pathways at the wB97x/6-31G(d) level of theory.

NeuralNEB -- Neural Networks can find Reaction Paths Fast

no code implementations20 Jul 2022 Mathias Schreiner, Arghya Bhowmik, Tejs Vegge, Peter Bjørn Jørgensen, Ole Winther

We also compare with and outperform Density Functional based Tight Binding (DFTB) on both accuracy and computational resource.

Equivariant graph neural networks for fast electron density estimation of molecules, liquids, and solids

1 code implementation1 Dec 2021 Peter Bjørn Jørgensen, Arghya Bhowmik

Electron density $\rho(\vec{r})$ is the fundamental variable in the calculation of ground state energy with density functional theory (DFT).

DeepDFT: Neural Message Passing Network for Accurate Charge Density Prediction

1 code implementation4 Nov 2020 Peter Bjørn Jørgensen, Arghya Bhowmik

We introduce DeepDFT, a deep learning model for predicting the electronic charge density around atoms, the fundamental variable in electronic structure simulations from which all ground state properties can be calculated.
