| subroutine, public | prg_response_mod::prg_compute_polarizability (rsp_bml, prt_bml, polarizability, factor, verbose) |
| | To compute the polarizability of the system. The units of the directional polarizability are determined by the units of the perturbation and Hamiltonian. This equation can be found in [5] equation 4a. Note that in equation 4a of the reference there is a 2 that account for the double occupancy which is not present in this case cause the density matrix construction is done by taking the occupancy into account.

| subroutine, public | prg_response_mod::prg_pert_constant_field (field, intensity, coordinate, lambda, prt_bml, threshold, spindex, norbi, verbose, over_bml) |
| | Apply a constant field perturbation through the dipole moment operator ( \( \hat{\mu} = e \hat{\textbf{r}} \)). In the matrix representation, this is: \( H^{(1)} = \lambda \frac{1}{2}(\,S \, e \textbf{r} \cdot \textbf{E} + \, e \textbf{r} \cdot \textbf{E}S) \). The symmetrization is done in order to preserve the Hermiticity of H. In this case the whole system will be affected by the field. In a latter version we will add the possibility of applying this field to a region of the system. In this implementation \( e= 1 \) and units can be transformed by using the parameter \( \lambda \).
