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.
