Second order perturbative correction to the wave function contained in the EZFIO directory.
|
|
|
|
|
|
|
|
|
|
This programs runs the stochastic PT2 correction on all "n_states" wave function stored in the EZFIO folder (see :option:`determinant n_states`).

The option for the PT2 correction are the "pt2_relative_error" which is the relative stochastic
|
|
|
|
|
|
|
|
|
|
error on the PT2 to reach before stopping the stochastic sampling. (see :option:`perturbation pt2_relative_error`)
