WebNov 10, 2014 · "Smearing" is not well-defined enough for that. If it just refers to wave functions spread out in space, then the double-slit experiment is enough to find something similar. Or a simple electron orbital in an atom. Sicktoaster said: Smearing you think of it smearing out to cover a wider area, which it does not appear to do. WebJan 15, 2024 · The Gaussian smearing method and a width of 0.05 eV was used for partial occupancies of the Kohn − Sham orbitals. The change of electronic energy was less than 10 −5 eV, which indicates a self-consistent energy. Moreover, the change of electronic energy was smaller than 5×10 −2 eV Å −1, suggesting convergence of geometric optimization. fisheye lens real estate photography https://speconindia.com
