* Configuration based CI
|
||||
|
||||
Here we write the main functions that perform the functions necessary for
|
||||
the Configuration based CI.
|
||||
|
||||
There are three main functions required for doing the CI
|
||||
|
||||
- Convert wavefunction from determinant basis to configuration state function (CSF) basis
|
||||
|
||||
- Apply the Hamiltonian to the wavefunction in CSF basis
|
||||
|
||||
- Convert the converged wavefunction back to determinant basis
|
||||
|
||||
** TODO[0/3] Convert basis from DET to CSF
|
||||
|
||||
The conversion of basis is done by going via bonded functions (BFs).
|
||||
Importantly, all the CSFs of a chosen configuration (CFG) are kept.
|
||||
|
||||
The advantage is that the sigma-vector can be performed efficiently
|
||||
via BLAS level 3 operations.
|
||||
|
||||
|
||||
- [ ] Write a function to calculate the maximum dimensions required
|
||||
|
||||
Prototype array contains the \( <I|\hat{E}_{pq}|J> \) for all possible
|
||||
CFGs \( I, J\) and all \(4\) types of excitations for all possible model
|
||||
orbitals \(p,q\). Note that the orbital ids \(p,q\) here do not refer to
|
||||
the actual MO ids, they simply refer to the orbitals involved in that spefcific
|
||||
SOMO, for e.g. an excitation of the type [2 2 2 1 1 1 1 0] -> [ 2 2 1 1 1 1 1]
|
||||
implies an excitation from orbital \(3\) to orbital \(8\) which are the real MO ids.
|
||||
However, the prototype only concerns the SOMOs like so [2 1 1 1 1 0] -> [ 1 1 1 1 1 1]
|
||||
therefore \(p,q\) are model space ids \(1,6\).

finally the two model space orbitals \(p,q\).
