Quick description
|
|
-----------------
|
|
|
|
The Range-separated Kohn-Sham module performs *Restricted* range-separated Hybrid calculation,
|
|
which means that only the long-range part of the *exact* exchange is taken into account.
|
|
|
|
The program associated to it is the :ref:`rs_ks_scf` executable.
|
|
|
|
.. seealso::
|
|
|
|
The documentation of the :ref:`module_dft_keywords` module for the various keywords
|
|
such as the exchange/correlation functionals or the range-separation parameter.
|
|
|
|
|
|
.. seealso::
|
|
To see the keywords/options associated to the |SCF| algorithm itself,
|
|
see the documentation of the :ref:`module_scf_utils` module.
|
|
|
|
|
|
More advanced description
|
|
-------------------------
|
|
|
|
The splitting of the interaction between long- and short-range is determined by the range-separation parameter :option:`ao_two_e_erf_ints mu_erf`. The long-range part of the interaction is explicitly treated with exact exchange, and the short-range part of the interaction is treated with appropriate DFT functionals.
|
|
|
|
The Range-separated Kohn-Sham in an SCF and therefore is based on the :ref:`module_scf_utils` structure.
|
|
|
|
The definition of the Fock matrix is in :file:`kohn_sham_rs fock_matrix_rs_ks.irp.f`
|
|

|
|
For a more detailed description of the |SCF| structure,
