Cannot project on zero atomic wavefunctions
WebNot all wavefunctions have nodes, the lowest energy one does not, (e.g. the S orbital in atoms, zero point vibration and zero rotation in molecules, lowest MO in a molecule). The larger the number of nodes a wavefunction has the greater the energy eigenvalue. Some pictures of wavefunctions and nodes has been given in the answer by @Brian. WebPurpose of projwfc.x: projects wavefunctions onto orthogonalized atomic wavefunctions, calculates Lowdin charges, spilling parameter, projected DOS (separated into up and …
