<p style="margin-top:0;margin-bottom:0">Dear QE community,</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">Apologies for bringing up a recurring theme and with such an elementary question. I can see from the archive that there is plenty of talk about the V_bare potential but none which answered my question, at least to my
understanding.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">I am interested in generating the electrostatic potential generated from a Quantum Espresso calculation using pp.x</p>
<p style="margin-top:0;margin-bottom:0">Referring to the input description:</p>
<p style="margin-top:0;margin-bottom:0"><a href="https://www.quantum-espresso.org/Doc/INPUT_PP.html" class="OWAAutoLink" id="LPlnk199143" previewremoved="true">https://www.quantum-espresso.org/Doc/INPUT_PP.html</a></p>
<p style="margin-top:0;margin-bottom:0">I am tempted to simply use "plot_num = 11", i.e. </p>
<pre style="margin-bottom: -1em;">>>11 = the V_bare + V_H potential</pre>
<p></p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">My reservation is that V_H is defined as <br>
</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0"></p>
<pre style="margin-bottom: -1em;">>>local ionic potential V_bare<br><br></pre>
<p></p>
<p style="margin-top:0;margin-bottom:0">The word "local" makes me concerned that this is a simple sum q/R of the pseudonuclei in the unit cell; in fact I would like the overall crystal potential calculated e.g. with an Ewald sum.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<ol style="margin-bottom: 0px; margin-top: 0px;">
<li>What does the word 'local' mean here?</li><li>Will "plot_num = 11" actually give me the crystal electrostatic potential, including the Hartree potential via FFT and ionic potential via Ewald sum?</li></ol>
