<div>Hi
</div>
<div>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.
</div>
<div>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.
