LIST AND CONTENT OF THE EXAMPLES
example01:
This example shows how to use pw.x and ph.x to calculate phonon
frequencies at Gamma and X for Si and C in the diamond structure and
for fcc-Ni.
example02:
This example shows how to calculate interatomic force constants in
real space for AlAs in zincblende structure.
example03:
This example shows how to calculate electron-phonon interaction
coefficients at X for fcc Al.
example04:
This example shows how to use pw.x and ph.x to calculate the
normal modes of a molecule (CH4) at Gamma
example05:
This example shows how to use pw.x and ph.x to calculate the Raman
tensor for AlAs.
example06
This example shows how to use ph.x to calculate the phonon frequencies
at Gamma and X and the dispersion for fcc-Pt with spin-orbit interactions.
example07:
This example tests pw.x and ph.x in several cases that require the
noncollinear or the spin-orbit part of the code together with the gga.
ph.x is used to calculate the phonons at X and Gamma of fcc-Pt with gga,
and to calculate the phonons at X and Gamma of fcc-Ni to test the magnetic
case with gga with or without spin-orbit (experimental stage).
example08:
This example tests ph.x together with PAW.
example09:
This example illustrates how to use pw.x and ph.x to calculate
dynamic polarizability of methane molecules (experimental stage)
example10:
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 (experimental stage).
example11:
This example tests pw.x and ph.x for the noncollinear/spin-orbit case
and PAW (still experimental).
example12:
This example shows how to use pw.x and phcg.x to calculate the normal
modes of a molecule (SiH4) at Gamma.
example13:
Full dispersions for spin-polarized phonons (Ni)
example14:
This example shows how to use ph.x to calculate the phonon frequencies
on an arbitrary set of q points. The points can be generated automatically
along paths or on a bi-dimensional plane.
example15:
This example shows how to create Infrared and Raman spectra using pw.x,
ph.x and dynmat.x
example16:
Graphite with DFT-D2 and with nonlocal vdW-aware functionals
example17:
This example shows how to compute the phonon dispersions of two-dimensional
materials
example18:
This example shows how to use pw.x and ph.x to calculate phonon frequencies
of LiCoO2 with Hubbard U on Co 3d states (experimental stage).
example19:
This example shows how to use ph.x, dvscf_q2r.x and postahc.x to calculate
electron-phonon renormalization of the band gap of diamond within the
Allen-Heine-Cardona (AHC) theory.
