[gpaw-users] Jellium slabs in PW mode do not work?

[Rasmus Karlsson]

Hi gpaw-users,
I am doing some work on adsorbates on jellium slabs, and have tried to
do that in GPAW. The examples on the web page work OK, and I ran
a few calculations with slabs and adsorbates on the slab. However,
when I became interested in plotting the density differences, I noticed
that there wasn't any density in the regions I expected.

It turns out that if you run e.g. the examples here:
https://wiki.fysik.dtu.dk/gpaw/tutorials/jellium/jellium.html in grid
mode, everything works OK. If you switch to PW mode, everything also
works without fail, but plotting Fig2 there shows that the density is
just 0 throughout the cell.

What is going on here? Am I correct in saying that jellium calculations
do not work in PW mode? If so, why is that?

Thanks,
Rasmus
