Drudeterm in RPA

Post by samaneh » Fri Oct 09, 2015 5:42 pm

Dear Developers,
I have a heavily doped semiconductor.
For the RPA calculations (without considering QP corrected database or any scissor operator)
I did not use any Drude term but in the report files I have some warning for that
So I used some values for Drude term
but the spectrum is not true
and it is different from the one with 0 values!!!
I have used other values but unfortunately I got the same spectrum
and the one with 0 values is more reliable!!!
I've attached two spectrum.
I would be thankful if you can help me with this problem.
Best regards

Next, it is not easy to understand what is happening form the plot. Please post input/output and report, so we can inspect what is going wrong.
