Regarding the matrix elements of the phonon velocity operator #219

Closed DI20028 closed 1 month ago

DI20028 commented 1 month ago

I want to calculate the matrix element of the phonon velocity operator (v^α_qbb') through Phoebe code. In addition to this, can I also calculate off-diagonal terms of the matrix element of the phonon velocity in which real and imaginary parts are included? If yes, then please discuss the procedure.
