|
|
==================
|
|
|
|
Here, all two-electron integrals (:math:`1/r_{12}`) are computed.
|
|
As they have 4 indices and many are zero, they are stored in a map, as defined
|
|
in :file:`utils/map_module.f90`.
|
|
|
|
To fetch an |AO| integral, use the
|
|
`get_ao_two_e_integral(i,j,k,l,ao_integrals_map)` function.
|
|
|
|
|
|
The conventions are:
|
|
* For |AO| integrals : (ij|kl) = (11|22) = <ik|jl> = <12|12>

subroutine two_e_integrals_index_reverse(i,j,k,l,i1)
|
|
|
|
|
|
Computes the 4 indices $i,j,k,l$ from a unique index $i_1$.
|
|
For 2 indices $i,j$ and $i \le j$, we have
|
|
$p = i(i-1)/2 + j$.
|
|
The key point is that because $j < i$,
|
|
$i(i-1)/2 < p \le i(i+1)/2$. So $i$ can be found by solving
|
|
$i^2 - i - 2p=0$. One obtains $i=1 + \sqrt{1+8p}/2$
|
|
and $j = p - i(i-1)/2$.
|
|
This rule is applied 3 times. First for the symmetry of the
|
|
pairs (i,k) and (j,l), and then for the symmetry within each pair.
