Correlation-consistent Gaussian basis sets for copper solids from material-constrained atomic optimization
Jincheng Yu, Xiaoyu Zhang, Min-Ye Zhang +3
Correlation-consistent Gaussian basis sets are central to systematic molecular quantum chemistry, but their direct use in periodic solids is often limited by severe linear dependen…
Eliminating Delocalization Error through Localized Orbital Scaling Correction with Orbital Relaxation from Linear Response
Yichen Fan, Jincheng Yu, Jiayi Du +1
Despite the great success that Kohn-Sham density functional theory (KS-DFT) has achieved, the delocalization error remains a major challenge for commonly used density functional ap…
