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:
|
|
.INDENT 0.0
|
|
.IP \(bu 2
|
|
number of Slater determinants > \fBdeterminants n_det_max\fP
|
|
.IP \(bu 2
|
|
abs(PT2) less than \fBperturbation pt2_max\fP
|
|
.UNINDENT
|
|
.sp
|
|
The following other options can be of interest:
|
|
.INDENT 0.0
|
|
.TP
|
|
.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\&.
