Dear QE users and developers, I am writing to ask for a small clarification in the formula that defines the electron-phonon coupling matrix element (Equation 1 in the phonon user guide: http://www.quantum-espresso.org/wp-content/uploads/Doc/ph_user_guide.pdf )
What is 'M' in Equation 1? Is it the total mass of the unit cell? Thanks, Sridhar Purdue University -------------- next part -------------- An HTML attachment was scrubbed... URL: http://pwscf.org/pipermail/pw_forum/attachments/20140517/65f22cc8/attachment.html
