Optimized auxiliary functions for robust mitigation of finite-size errors in periodic hybrid density functional theory
Stephen Jon Quiton, Juan D. F. Pottecher, Xin Xing +2
When calculating properties of periodic systems at the thermodynamic limit (TDL), the dominant source of finite size error (FSE) arises from the long-range Coulomb interaction, and…
