Smearing and Broadening
Posted: Mon May 28, 2018 6:12 pm
Hello all users,
I have question on smearing and broadening process on dielectric function calculation.
I knew that "ISMEAR" and "SIGMA" are related to smearing which changes the occupation of eigenstates.
But, what I want to do is uses very small smearing with specific broadening on dielectric function.
Thus, is there any option to control the broadening?
