Dear Paul,

How are you?  I hope you are fine and enjoying the holidays.

I filled out the tie card today.  I saw one of the funding is  not there: the TE funding.  The ABSCO, I think, will be out in the next week.  If you don’t mind, could you renew these 2 funding if possible.  You don’t have to do it now, since it is holiday time now, and you probably have your own plan in the holidays.   I just let you know in advance since the week after New Year, I will need them for charging the time card.

I emailed you the data last week of the nscf run using the scf 9x9x9.  I am waiting for your calculation of Seebeck coefficient, so that I can decide whether I should run the scf 9x9x9 for the one atom case.   I don’t mean to ask you to do it now since it is your holidays, and you need to enjoy too.

I will fly back on Jan. 3, and from Jan 4 to Jan 6, I have class.  I am not sure if I can do anything much after the class.  I will try to work if I am not very tired.    See you after Jan. 6.

HAPPY NEW YEAR!

Trinh

Dear Zhou,

It is a good idea citing  the paper as it contains all formulas used to calculate \lambda.

Bests,
Eyvaz.

Dear Eyvaz,
Thanks a lot for such quick response. I want to know the current method which is just implemented in espresso-4.2.1.
I guess it may be arXiv:cond-mat/0504077v2 <http://arxiv.org/abs/cond-mat/0504077v2>  with the title "Origins of low- and high-pressure discontinuities of Tc in niobium".
But I am not very sure about it.
Best regards,
Xiang-Feng Zhou
