HI there,
I'm using the Vasp 5.2.2 and now i started to use the vasp 5.3.2
I noticed a BIG (0.4 eV) difference for the ZnO band gap when using GW0.
Any ideas where it came from?
The input parameters are the same for both calculations.

Difference between GW0 and what else?

The difference is between GW0 in Vasp5.2.2 and GW0 in Vasp5.3.2.
In a fast talk between my colleagues, seems that HSE is also with a small change in the energy gap between the 5.2 and the 5.3 version.
it can be and update in some functions, but ZnO is quite hard to get proper values.
Any Idea?
