Dear Stefano Baroni :
Thank you for your reply.
I have another question want to ask you. Can you tell me? Thank you
in advance!
In your paper ??PRB??57??10421??1998??????you have discussed the
phase transition of alpha-Sn to beta-Sn by compared their free energy. Now,
I want to research the effect of pressure on the transition temperature. So
I want to know, it is feasible to research the effect of pressure on the
transition temperature by compare the free energy under different pressure?
Thanks a lot!
