EAC-Net: Predicting real-space charge density via equivariant atomic contributions
Xuejian Qin, Taoyuze Lv, Zhicheng Zhong
Charge density is central to density functional theory (DFT), as it fully defines the ground-state properties of a material system. Obtaining it with high accuracy is a computation…
