[Sax-project-users] quasi particale band structure

[kazempoor at ph.iut.ac.ir]

Dear All
According to previous emails , you said that for doing band structure plot we can do  two step procedure 
one determine a function that gives the
GW correction with respect to DFT values (usualy linear): in the second
one do a program that according to DFT energies as function of k points
correct with GW-correction (this can be done modifying the
Quantum-espresso code that calculates the band structure).

could you please explain first step in more detaails?what do you mean by usually linear? Do you mean GW correction do constant shift  in energy level in each k-point ?
Another question is How can i define High symmetry kpoints( that comes into band structure plot) in my GW calculation?
thanks a lot
