Setting up pseudopotentials - University of Cambridge

WebSummary. The fundamental idea of a “pseudopotential” is the replacement of one problem with another. The primary application in electronic structure is to replace the strong Coulomb potential of the nucleus and the effects of the tightly bound core electrons by an effective ionic potential acting on the valence electrons. Web在现代的平面波电子结构数值计算中，范数守恒（Norm-conserving）和超软（Ultrasoft）有效势是两种最常用的有效势。这两种有效势使基组可用较低的截断频率（即傅里叶展开项中的最高频率）来描述电子的波函数，从而在有限的计算资源下达到一定的数值收敛。 toyah willcox children
