[Pw_forum] help:Sn phase transition

[hailin yu]

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!
