WebThe pseudopotential theory began as an extension of the OPW method. It is based on an ansatz which separates the total wave function into an oscillatory part and a smooth part, the so called pseudo wave function. The strong true potential of the ions is replaced by a weaker potential valid for the valence electrons. What is Encut in VASP?
