About calculating macro quantity using DFT ?

[Tianshu Jiang in Beijing]

Hello everyone, 
I have been studying with CP2K for over 6 months, and consistently received 
help from different people. 
My specialty locates in calculation mathematics, so for the complex 
chemical process or physical process, I did not figure it out to be honest.
I leaned the basic DFT theory and knew the fundamental area. As for the use 
CP2K, I can understand the meaning and do some simple calculation.

Now I need to calculate some macro quantity for graphene based on DFT, such 
as permittivity or absorption coefficient. Of course, some other methods, 
like 
Monte Carlo simulation or molecular dynamics, can be use to calculate the macro 
quantity more easily, but I must use DFT.
I have looked all over the tutorial on official website, but there is 
rarely a similar example. 

Therefore, I want to ask you for help. Which macro quantities can be 
simulated using CP2K ? Or have you ever calculated some macro quantities ?
Thanks for your kind reply !
