<div dir='auto'>Hi<div dir="auto">In fact you can download upf pseudopotentials from pseudodojo as well. You need to select the format before downloading. </div><div dir="auto">Regards Pietro</div></div><div class="gmail_extra"><br><div class="gmail_quote">Il 28 apr 2020 4:44 AM, Hongyi Zhao <hongyi.zhao@gmail.com> ha scritto:<br type="attribution" /><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p dir="ltr">Hi,
<br>
<br>
I noted the following github repo: https://github.com/pipidog/ONCVPSP
<br>
which told the following things:
<br>
<br>
------------------------------------------
<br>
Optimized Norm-Conserving Vanderbilt Pseudopotential (ONCVPSP) is an
<br>
accurate and inexpansive NCPP:
<br>
https://journals.aps.org/prb/abstract/10.1103/PhysRevB.88.085117
<br>
Currnetly there are two major ONCVPSP database, one is provided by
<br>
ABINIT's official website:
<br>
http://www.abinit.org/downloads/pseudodojo/pseudodojo
<br>
The other one is provided by sg15 database:
<br>
http://www.quantum-simulation.org/potentials/sg15_oncv/
<br>
<br>
The former is in psp8 format which is not compatible with Quantum
<br>
Espresso (QE). The later is already in UPF format but these ONCVPSPs
<br>
do not contain the PSWFC section (wave functions in PSP) which is
<br>
required by projwfc.x, the code in QE to calculate PDOS and fatband,
<br>
to project. As a result, neither of them is fully compatible with QE
<br>
and, more importantly, neither one provide fully-relativisitc version
<br>
(needed for spin-orbit coupling).
<br>
<br>
In short, you will always need to regenerate your own ONCVPSP in most
<br>
QE calculatons especially when it comes to spin-orbit coupling.
<br>
------------------------------------------------
<br>
<br>
Based on the above description, the sg15_oncv supplied here
<br>
http://www.quantum-simulation.org/potentials/sg15_oncv/, has not the
<br>
out-of-the-box feature for Quantum ESPRESSO.
<br>
<br>
On the other hand, the https://github.com/pipidog/ONCVPSP itself was
<br>
recently updated 2017, so it maybe outdated.
<br>
<br>
As a result, I still confused on the selection of ONCVPSP
<br>
pseudopotential suitable for Quantum ESPRESSO. Could you please give
<br>
some hints on this issue?
<br>
<br>
Thanks a lot in advance.
<br>
<br>
Regards
