That helps a lot ! But I do not understand why the code returns "0" occupation number for all bands when I use "calculation='bands' because that is when I add more k-points and would ideally then want the occupation numbers. Am I doing something improper or the code is set up in that manner ? Part

[Pw_forum] band population / smearing parameter

2013-12-03 Thread Partha Pal
Dear All, I am looking to "fine tune" the smearing parameter (degauss=? with gaussian smearing) of a hydrogen_graphene system to estimate the smallest possible value. I need the value of smearing to capture the "true broadening" of the peak in hydrogen PDOS/LDOS when it interacts with the quasi-c
