LVTOT
LVTOT = [logical]
Default: LVTOT = .FALSE.
Description: Determines whether the total local potential [math]\displaystyle{ V_{\text{LOCPOT}}(\mathbf{r}) }[/math] (in eV) is written to the LOCPOT file.
[math]\displaystyle{ V_{\text{LOCPOT}}(\mathbf{r}) = V_{\text{ionic}}(\mathbf{r}) + \int \frac{n(\mathbf{r'})}{|\mathbf{r}-\mathbf{r'}|}d\mathbf{r'}+ V_{\text{xc}}(\mathbf{r}) }[/math]
where [math]\displaystyle{ V_{\text{ionic}}(\mathbf{r}) }[/math] is the ionic potential, the second term is the Hartree potential, and [math]\displaystyle{ V_{\text{xc}}(\mathbf{r}) }[/math] is the (semi-)local exchange-correlation potential.
If LVTOT=.TRUE., the [math]\displaystyle{ V_{\text{LOCPOT}}(\mathbf{r}) }[/math] is written to the LOCPOT file and the POT file. The POT file additionally contains the augmentation part.
| Warning: LVHAR=T changes the content of the LOCPOT file. |
WRT_POTENTIAL also gives access to the total local potential and offers more options.
