Dear all
I have a problem about the GW method. In the forum, I found some people
said GW allows to address large systems (a few hundreds of atoms).But I don't
know where ? We know the course of computing the GW quasi-particle energies is
the following :
1. pw.x
2. pw4gww.x
3. gww.x
If we want to calculate a large system, we must optimized it first with pw.x
which is still time-consuming. So I want to know what makes the GW code can
calculate the large system and where it reflects in the course of using GW code
?
