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| directory (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`
|

|
.. 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
|
|
|
|
.. option:: no_core_density
|
|
|
|
if [no_core_dm] then all elements of the density matrix involving at least one orbital set as core are set to zero
|
|
|
|
Default: full_density
