    • We will use the term "wave function" as an abbreviation for "single electron wave function" in the context of KS-DFT, not to be confused with a many-body wave function.

    • note
    • Note that our current implementation is restricted to real wave functions, due to the nonperiodic nature of the systems. Despite that, the usual nomenclature, as well as the definition of the fictitious kinetic energy without the factor of one-half for complex wave functions, are used, in accordance with the general style of publications on the subject.

    • This is just an approximate consideration, taking only the second derivative of the electronic kinetic energywith respect to the value of the wave function at a grid point into account. See also ref. 52.

    • note
    • The parameter ω defines the extent of "overcorrection" of the potential values during a sweap of the solver. The standard Gauss-Seidel Algorithm without over-relaxation is recovered for ω = 1.0. For further details on the SOR algorithm and its implementation see ref. 81.
