Higher-Order Equivariant Neural Networks for Charge Density Prediction in Materials

1 code implementation8 Dec 2023 Teddy Koker, Keegan Quigley, Eric Taw, Kevin Tibbetts, Lin Li

The calculation of electron density distribution using density functional theory (DFT) in materials and molecules is central to the study of their quantum and macro-scale properties, yet accurate and efficient calculation remains a long-standing challenge in the field of material science.
