CISD
|
|
====
|
|
|
|
This is a test directory which builds a CISD by setting the follwoing rules:
|
|
|
|
* The only generator determinant is the Hartee-Fock (single-reference method)
|
|
* All generated determinants are included in the wave function (no perturbative
|
|
selection)
|
|
|
|
These rules are set in the ``H_apply.irp.f`` file.
|
|

`h_apply_cisd <http://github.com/LCPQ/quantum_package/tree/master/src/CISD/H_apply.irp.f_shell_8#L406>`_
|
|
Calls H_apply on the HF determinant and selects all connected single and double
|
|
excitations (of the same symmetry). Auto-generated by the ``generate_h_apply`` script.
|
|
|
|
|
|
`h_apply_cisd_diexc <http://github.com/LCPQ/quantum_package/tree/master/src/CISD/H_apply.irp.f_shell_8#L1>`_
|
|
Generate all double excitations of key_in using the bit masks of holes and
|
|
particles.
|
|
Assume N_int is already provided.
|
|
|
|
|
|
`h_apply_cisd_monoexc <http://github.com/LCPQ/quantum_package/tree/master/src/CISD/H_apply.irp.f_shell_8#L263>`_
|
|
Generate all single excitations of key_in using the bit masks of holes and
|
|
particles.
|
|
Assume N_int is already provided.
