[Pw_forum] phonon dispersion by using optimized tetrahedron method

[Mitsuaki Kawamura]

Dear Dr. Enamul Haque

Hello,

QE v 6.2.1 supports the calculation of the phonon dispersion interpolated from the result of DFPT with the optimized tetrahedron method.

Best regards,
Mitsuaki Kawamura

Subject: [Pw_forum] phonon dispersion by using optimized tetrahedron method

Dear  PWSCF users 

I  am very interested to calculated the e-ph constant by using both tetrahedron and interpolated method. I can do both task. The problem is that I cannot calculate the phonon dispersion by using tetrahedron method, and I do not find any source to solve this, although I can do this by using interpolated method. Since q2r code does not work in tetrahedron method, how can I run matdyn?

It would be a great pleasure for me if you help me in this regard. 

Thank you for your time!
