#+TITLE: Molecular Orbitals
|
|
#+SETUPFILE: ../tools/theme.setup
|
|
#+INCLUDE: ../tools/lib.org
|
|
|
|
The molecular orbitals (MOs) are defined in the basis of AOs along with a AO to MO
|
|
coefficient matrix \[C\]. Using these coefficients (e.g. from Hartree Fock SCF method)
|
|
the MOs are defined as follows:
|
|
|
|
\[
|
|
\phi_i(\mathbf{r}) = C_i * \chi_i (\mathbf{r})
|
|
\]
|
|
|
|
|
|
In this section we demonstrate how to use the QMCkl specific DGEMM
|
|
function to calculate the MOs.

The following arrays are stored in the context:
|

|
|
|
|
|---------------+--------------------+----------------------|
|
|
| ~mo_num~ | | Number of MOs |
|
|
| ~coefficient~ | ~[mo_num][ao_num]~ | Orbital coefficients |
|

|
|
Computed data:
|
|
|
|
|---------------+--------------------------+-------------------------------------------------------------------------------------|

|
|
| ~mo_vgl~ | ~[point_num][5][mo_num]~ | Value, gradients, Laplacian of the MOs at point positions |
|
|

** Data structure
|

The ~uninitialized~ integer contains one bit set to one for each

initialization function which has not been called. It becomes equal

to zero after all initialization functions have been called. The

|
struct is then initialized and ~provided == true~.
|
|
Some values are initialized by default, and are not concerned by
|
|
this mechanism.
