============
The Hartree-Fock module performs *Restricted* Hartree-Fock calculations (the
spatial part of the |MOs| is common for alpha and beta spinorbitals).
The :ref:`scf` program performs *Restricted* Hartree-Fock
calculations (the spatial part of the |MOs| is common for alpha and beta
spinorbitals).
The Hartree-Fock in an SCF and therefore is based on the ``scf_utils`` structure.
It performs the following actions:
The Hartree-Fock algorithm is a |SCF| and therefore is based on the
:ref:`module_scf_utils`` module.
#. Compute/Read all the one- and two-electron integrals, and store them in memory
#. Check in the |EZFIO| database if there is a set of |MOs|. If there is, it
will read them as initial guess. Otherwise, it will create a guess.
#. Perform the |SCF| iterations
The definition of the Fock matrix is in :file:`hartree_fock fock_matrix_hf.irp.f`
For the keywords related to the |SCF| procedure, see the ``scf_utils`` directory where you will find all options.
The main are:
# :option:`scf_utils thresh_scf`
# :option:`scf_utils level_shift`
At each iteration, the |MOs| are saved in the |EZFIO| database. Hence, if the calculation
crashes for any unexpected reason, the calculation can be restarted by running again
the |SCF| with the same |EZFIO| database.
The `DIIS`_ algorithm is implemented, as well as the `level-shifting`_ method.
If the |SCF| does not converge, try again with a higher value of :option:`level_shift`.
To start a calculation from scratch, the simplest way is to remove the
``mo_basis`` directory from the |EZFIO| database, and run the |SCF| again.
.. _DIIS: https://en.wikipedia.org/w/index.php?title=DIIS
.. _level-shifting: https://doi.org/10.1002/qua.560070407
The Fock matrix is defined in :file:`hartree_fock fock_matrix_hf.irp.f`.

Configuration Interaction with Single excitations.
.sp
This program takes a reference Slater determinant of ROHF\-like
occupancy, and performs all single excitations on top of it.
Disregarding spatial symmetry, it computes the \fIn_states\fP lowest
eigenstates of that CI matrix. (see \fBdeterminants n_states\fP)
.sp
This program can be useful in many cases:
.sp
To be sure to have the lowest SCF solution, perform an scf
(see the hartree_fock module), then a \fI\%cis\fP, save
the natural orbitals (see save_natorb) and re\-run an
scf optimization from this MO guess.
.sp
The lowest excited states are much likely to be dominated by
single\-excitations. Therefore, running a \fI\%cis\fP will save
the \fIn_states\fP lowest states within the CIS space in the \fI\%EZFIO\fP
directory, which can afterwards be used as guess wave functions for
a further multi\-state FCI calculation if \fBdeterminants read_wf\fP
is set to \fBtrue\fP before running the fci
executable.
.sp
If \fBdeterminants s2_eig\fP is set to \fBtrue\fP, the CIS
will only retain states having the expected \ewidehat{S^2} value (see
\fBdeterminants expected_s2\fP). Otherwise, the CIS will take
the lowest \fBdeterminants n_states\fP, whatever multiplicity
they are.

Selected Full Configuration Interaction with stochastic selection
and PT2.
.sp
This program performs a CIPSI\-like selected CI using a
stochastic scheme for both the selection of the important Slater
determinants and the computation of the PT2 correction. This
CIPSI\-like algorithm will be performed for the lowest states of
the variational space (see \fBdeterminants n_states\fP). The
FCI program will stop when reaching at least one the two following
conditions:

.B \fBdeterminants read_wf\fP
When set to \fBfalse\fP, the program starts with a ROHF\-like Slater
determinant as a guess wave function. When set to \fBtrue\fP, the
program starts with the wave function(s) stored in the \fI\%EZFIO\fP
directory as guess wave function(s).
.TP
.B \fBdeterminants s2_eig\fP
When set to \fBtrue\fP, the selection will systematically add all the
necessary Slater determinants in order to have a pure spin wave
function with an \ewidehat{S^2} value corresponding to
\fBdeterminants expected_s2\fP\&.
.UNINDENT
.sp
For excited states calculations, it is recommended to start with
\&.cis. or \&.cisd. guess wave functions, eventually in
a restricted set of MOs, and to set \fBdeterminants s2_eig\fP
to \fBtrue\fP\&.

Check in the \fI\%EZFIO\fP database if there is a set of MOs\&.

At each iteration, the MOs are saved in the \fI\%EZFIO\fP database. Hence,
if the calculation crashes for any unexpected reason, the calculation
can be restarted by running again the SCF with the same \fI\%EZFIO\fP
database.

To start again a fresh SCF calculation, the MOs can be reset by
running the qp_reset command.

method. If the SCF does not converge, try again with a higher value of
