density_for_dft
===============


This module defines the *provider* of the density used for the DFT related calculations. 
This definition is done through the keyword :option:`density_for_dft density_for_dft`. 
The density can be: 

* WFT : the density is computed with a potentially multi determinant wave function (see variables `psi_det` and `psi_det`)# input_density : the density is set to a density previously stored in the |EZFIO| folder (see ``aux_quantities``)
* damping_rs_dft : the density is damped between the input_density and the WFT density, with a damping factor of :option:`density_for_dft damping_for_rs_dft`




EZFIO parameters
----------------

.. option:: density_for_dft

    Type of density used for DFT calculation. If set to WFT , it uses the density of the wave function stored in (psi_det,psi_coef). If set to input_density it uses the one-body dm stored in aux_quantities/ . If set to damping_rs_dft it uses the damped density between WFT and input_density. In the ks_scf and rs_ks_scf programs, it is set to WFT.

    Default: WFT

.. option:: damping_for_rs_dft

    damping factor for the density used in RSFT.

    Default: 0.5
