dft_one_e
=========
This module defines the most important providers needed for the |DFT| and |RSDFT| calculations:
* :c:data:`energy_x` and :c:data:`energy_c` : the *exchange* and *correlation* energy functionals (see :file:`e_xc_general.irp.f`)
* :c:data:`potential_x_alpha_ao` and :c:data:`potential_x_beta_ao` : the exchange potential for alpha/beta electrons (see :file:`pot_general.irp.f`)
* :c:data:`potential_c_alpha_ao` and :c:data:`potential_c_beta_ao` : the correlation potential for alpha/beta electrons (see :file:`pot_general.irp.f`)
These providers are then used in the :ref:`ks_scf` and :ref:`rs_ks_scf` programs, together within some |RSDFT| external
plugins (see `<https://gitlab.com/eginer/qp_plugins_eginer>`_).
The flexibility of the functionals is handle by the two following keywords (see :ref:`module_dft_keywords`):
* :option:`dft_keywords exchange_functional` : defines which *exchange* functionals will be set
* :option:`dft_keywords correlation_functional` : defines which *correlation* functionals will be set
In the core modules of the |QP|, two functionals are implemented:
* "LDA" or "short_range_LDA" for, respectively the |LDA| and its short-range version
* "PBE" or "short_range_PBE" for, respectively the |PBE| and its short-range version
