[Pw_forum] about elph calculations

[Mehrnaz Anvari]

Hi 
I have a question about elph calculations in graphene. well, in graphene the 
electronic density of state at fermi surface is zero, so it could be a 
problem during elph calculations.
However according to Lazzeri's paper(PRL,vol93,2004)these equations could be 
restated to solve this problem. Now I want to know whether this correction 
has been implemented in PWscf package or not.I've done elph calculations for 
graphene and apperantly no problems exist, I mean up to now I've not got any 
problem, but I want to become sure.
