<div dir="ltr">Hi Kayahan,<br><br>I'm not familiar with the upf2casino converter but as far as I know the local channel in the SG-15 pseudopotentials is the "smooth polynomial continuation of the all-electron potential" and not an angular momentum component.

<br>
I am trying to convert SG-15 pseudopotentials -PP- into CASINO format (a popular Quantum Monte Carlo -QMC- code) using upf2casino.x in Quantum Espresso distribution under /upftools directory.<br>
<br>
However, the converted pseudopotential seems to get negative values for the local angular momentum channel. I think it is because “l_local" parameter is also set to the same value in the PP_HEADER section of the .UPF file and the conversion script assumes that it is the local channel. Right now I am testing the converted PP assuming that l_local-l_max which means that the maximum angular momentum orbital is actually the local channel.<br>
<br>
Is there anybody else who has such experience with the PP? What else should I be looking for in order to understand the conversion is right? I would look for some physical properties normally in DFT, but doing them in QMC takes a very long time.<br>
<br>
Thanks a lot in advance!<br>
<br>
Best,<br>
Kayahan<br>
