Dear all, Greetings!
I have a simple question. In the appendix of the user guide (http://www.quantum-espresso.org/wp-content/uploads/Doc/ph_user_guide/node12.html), the electron-phonon coefficient has a factor (1/M)^0.5. This is calculated in the ph.x program. Is the M the total mass of the unit cell, or reduced mass, or averaged mass? Thanks very much. regards, Xiaodong Li North Carolina State University, NC, US -------------- next part -------------- An HTML attachment was scrubbed...
