Hello,
I have completed a calculation using the SternheimerGW code in the
example section for Silicon. I am having trouble interpreting the output
of the code. Would someone help me figure out what is output? I'm mostly
concerned with the output for the self energy, the spectral function,
and the dielectric function. Example output is as follows:
Number of symmops in Small G_q: 1
ngmpol 59 and ngmunique 59
iq 8 igstart 1 igstop 59
eps_{GG}(q,w) = 2.93243 0.00000
eps_{GG}(q,w) = 2.92786 0.00000
eps_{GG}(q,w) = 2.89352 -0.00000
eps_{GG}(q,w) = 2.79858 -0.00000
eps_{GG}(q,w) = 2.63878 0.00000...
