[QE-users] Intraband plasma frequency

[周巍青]

Hi all,

I want to obtain the plasma frequency (intraband contribution), which has been implemented in VASP and WIN2K. In DFT,  plasma frequency can be calculated by an integral over the Fermi surface (see detail in Eq.5 in PHYSICAL REVIEW B 79, 125117 (2009)). I want to know it is possible to obtain intraband plasma frequency from PWscf output?
