Dear all, I have a question related to the wave functions in the phonon code. I think the wave function at the finite q vector (xq variable) \Psi_n(k+q) is contained in the evq variable. This wave function appears different from the wave function at an equivalent q point, for instance if I look at evq at q=(0,0,1), this is different from evq at (1,1,0) that are equivalent by translation of a G vector (I am thinking here at a FCC periodic lattice). The two functions just differ by a phase factor or I am missing something ?
Thanks in advance, Jacopo Simoni, Lawrence Berkeley National Lab.
