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…

The Staggered Mesh Method: Accurate Exact Exchange towards the Thermodynamic Limit for Solids
Stephen Jon Quiton, Hamlin Wu, Xin Xing +2
In periodic systems, the Hartree-Fock (HF) exchange energy exhibits the slowest convergence of all HF energy components as the system size approaches the thermodynamic limit. We de…
