[Pw_forum] Fermi surface nesting function

[Shanavas K. V.]

Hi all,

I am trying to write a code to calculate fermi surface nesting function
for an AFM system. 
Is there any code already available for it? I found a paper
http://arxiv.org/pdf/cond-mat/0504077 using the NF, but can somebody
guide me to some paper that explain the basic theory & method that can
help in writing the code?

Thanks in advance,

regards,
shanavas
