dir_file(filename=None, filename_base='')

File of the current Sile

read(*args, **kwargs)

Generic read method which should be overloaded in child-classes

Parameters:

kwargs – keyword arguments will try and search for the attribute read_<> and call it with the remaining **kwargs as arguments.

read_density_matrix(**kwargs) → DensityMatrix

Returns the density matrix from the siesta.DM file

Parameters:

  • geometry (Geometry, optional) – attach a geometry object to the sparse matrix

  • overlap (SparseMatrix, optional) – attach the overlap matrix to the sparse matrix

read_energy_density_matrix(**kwargs) → EnergyDensityMatrix[source]

Returns the energy density matrix from the siesta.TSDE file

Parameters:

  • geometry (Geometry, optional) – attach a geometry object to the sparse matrix

  • overlap (SparseMatrix, optional) – attach the overlap matrix to the sparse matrix

read_fermi_level() → float[source]

Query the Fermi-level contained in the file

Returns:

float – fermi-level of the system

write(*args, **kwargs)

Generic write method which should be overloaded in child-classes

Parameters:

**kwargs – keyword arguments will try and search for the attribute write_ and call it with the remaining **kwargs as arguments.

write_density_matrices(DM, EDM, Ef=0.0, **kwargs)[source]

Writes the density matrix to a siesta.DM file

Parameters:

  • DM (DensityMatrix) – density matrix to write to the file

  • EDM (EnergyDensityMatrix) – energy density matrix to write to the file

  • Ef (float, optional) – fermi-level to be contained

write_density_matrix(DM, **kwargs)

Writes the density matrix to a siesta.DM file
