triqs_dft_tools.sumk_dft_transport.raman_vertex
- triqs_dft_tools.sumk_dft_transport.raman_vertex(sumk, ik, direction, code, isp, options=None)[source]
Reads all necessary quantities for transport calculations from transport subgroup of the hdf5 archive. Performs checks on input. Uses interpolation if code=wannier90.
- Parameters:
- sum_ksum_k object
triqs SumkDFT object
- ikinteger
the ik index in which will be calculate the raman vertex
- directionstring
direction to calculate the Raman vertex.
- codestring
DFT code from which velocities are being read. Options: ‘wien2k’, ‘wannier90’
- ispinteger
spin index
- optionsdictionary, optional
additional keywords necessary in case a new direction wants to be implemented
- Returns:
- raman_vertex2D array
numpy array size [n_orb, n_orb] of complex type
