[Pw_forum] Dear Professor

[Stefano Baroni]

Dear Hua Peng: please, refer to the pw_form mailing list that you can

http://www.pwscf.org
The calculation of phonon lifetimes from third-order perturbaton  
theory is discussed, e.g., in
A. Debernardi, S. Baroni, and E. Molinari, Phys. Rev. Lett. 75, 1819 -  
1822 (1995)
See also Dbernardi's PhD thesis: Anharmonic Properties of  
Semiconductors from Density Functional Perturbation Theory
Best wishes - SB
