QE7.6 dynmat on actual archived zincblende GaN 2-atom Gamma DFPT matrix.
module load ase/3.29.0 qe/7.6-8173m; bash read.sh; bash plot.sh. Optional bash run.sh; bash read.sh work-new analysis-new; bash plot.sh analysis-new.
Six actual native cases: no ASR, simple/crystal ASR, TO and directional LO x/z. Reuses old 4^3 electronic and2^3q coarse DFPT source; original Born-charge sum about-0.57409e remains explicit, no convergence claim.
q(1..3) in dynmat input is the Cartesian non-analytic limiting direction, not a new finite phonon q. Mode eigenvector residuals and all frequencies independently calculated from the archived Cartesian matrix, given masses, dielectric tensor and charges.
