G0W0 spectral functionΒΆ
This examples shows how to plot the G0W0 spectral functions A(w) at the gamma point. See also lesson tgw2_4
import abipy.data as abidata
from abipy.abilab import abiopen
# Open the file with the GW results
sigres = abiopen(abidata.ref_file("al_g0w0_sigmaw_SIGRES.nc"))
# Plot A(w) for the first spin, the gamma point, and all bands
sigres.plot_spectral_functions()
# Only bands in [0, 1, 2]
sigres.plot_spectral_functions(spin=0, kpoint=(0, 0, 0), include_bands=range(0, 3))
