This example tests pw.x and ph.x for the effective charges and
dielectric constants with the noncollinear or the spin-orbit part of the
code. The collinear version for insulators with fixed total magnetization is
also tested.
The calculation proceeds as follows:
1) make a self-consistent calculation for Si
(input=si.scf.in, output=si.scf.out).
2) make a phonon calculation at the Gamma point (input=si.phG.in,
output=si.phG.out).
3) make a self-consistent calculation for C
(input=c.scf.in, output=c.scf.out).
4) make a phonon calculation at the Gamma point (input=c.phG.in,
output=c.phG.out).
5) make a self-consistent calculation for O2 molecule treated as an insulator
with LSDA and the total magnetization per cell constrained to 2.
(input=o2.scf.in, output=o2.scf.out)
6) make a phonon calculation at the Gamma point and calculate the dielectric
constant, Born effective charges in two ways and the vibrational modes
(input=o2.phG.in, output=o2.phG.out).
7) make a self-consistent calculation for the O2 molecule treated as an
insulator with noncollinear magnetization.
(input=o2_nc.scf.in, output=o2_nc.scf.out)
8) make a phonon calculation at the Gamma point for the O2 molecule
treated as an insulator with noncollinear magnetization.
(input=o2_nc.phG.in, output=o2_nc.phG.out)
