LIST AND CONTENT OF THE EXAMPLES
example01:
This example shows how to use pw.x and postprocessing codes to
make a contour plot in the [110] plane of the charge density for
Si, and to plot the band structure of Si.
example02:
This example shows how to use pw.x to calculate the DOS of Ni
and how to plot the Fermi Surface using XCrysDen
example03:
This example shows a calculation of STM maps.
example04:
This example shows how to use bands.x to check the band symmetry
of fcc-Pt with a fully relativistic pseudo-potential including
spin-orbit coupling, and to compute the projected DOS.
example05:
This example shows how to use pmw.x to generate better projectors for
LDA+U calculation on FeO. Read file README for more details
example06:
This example calculates the band structure of ferromagnetic bcc-Fe
in the noncollinear spin-orbit case.
projected_bands_example:
This example shows how to produce projected ("fat") band plots
dipole_example:
This example will calculate the water dipole and calculate the work
function on a Ni slab with a CO molecule adsorbed using the dipole
correction.
CLS_IS_example, CLS_FS_example
These examples show how to calculate initial-state (IS) and final-state (FS)
core-level-shift (CLS) using the core-excited pseudo-potential technique.
WorkFct_example:
This example shows how to use pw.x, pp.x, and average.x to
compute the work function of a metal using the slab-supercell
approximation. This example is of a 4 layer unrelaxed Al(100) slab
with 5 equivalent layers of vacuum between the surfaces.
WAN90_example:
This example shows how to use pw2wannier90.x in conjunction with
Wannier90 (http://www.wannier.org) to obtain maximally-localised
Wannier functions (MLWFs) for the valence bands of diamond.
WannierHam_example:
This example shows how to generate a model Hamiltonian in a
Wannier functions basis, using pw.x and wannier_ham.x.
MolDos_example:
This example calculates the projection of the density of states of
a system, containing a molecule, on the molecular orbitals of the
molecule (separately computed).
ForceTheorem_example:
This example shows how to compute the magnetic anisotropy energy (MAE)
with the "Force Theorem" method (Phys. Rev. B 90, 205409 (2014), and to
get its local decomposition over atomic orbitals using projwfc.x.
fermisurf_example:
This example generate input files for FermiSurfer
(http://osdn.jp/projects/fermisurfer/) to display Fermi surfaces with
color plots of the magnitude of the Fermi velocity and orbital characters.
BGW_example:
This example generates output files for BerkeleyGW using the pw2bgw.x
utility
ACF_example:
This example tests the ppacf.x utility

W90_open_grid_example:
This shows how to obtain Wannier functions without doing the intermediate
non-self consistent calculation, which is replaced by the utility open_grid.x
See also WAN90_example for the standard procedure.
exx_scf_bands_example:
This example shows how to use pw.x to calculate the band structure of Silicon
using hybrid HSE functional, including zero-weight dummy k-points. in the scf
calculation.
exx_interpolated_bands_example:
Here it is shown how to use pw.x and band_interpolation.x to calculate the
band structure of Silicon using PBE and hybrid PBE0 functionals, and
interpolating the band energies at the uniform Monkhorst-Pack grid of one scf
calculation.
