#+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 method)
|
|
the MOs are defined as follows:
|
|
|
|
\[
|
|
\phi_i(\mathbf{r}) = C_i * \chi_i (\mathbf{r})
|
|
\]
|
|
|
|
By default, all the MOs are computed. A subset of MOs can be selected
|
|
for computation, for example to remove computation of the useless
|
|
virtual MOs present in a MO coefficient matrix.
|
|
|
|
For each nucleus, a radius $r_{\text{cusp}}$ can be given such that if
|
|
the electron-nucleus distance is smaller than $r_{\text{cusp}}$, all
|
|
the MOs are replaced by functions with the correct cusp condition and
|
|
such that the values and the gradients of the MOs are continuous at
|
|
$r_{\text{cusp}}$.
|
|
|
|
|
|
|
|
Molecular orbitals (MOs) are defined in the basis of atomic orbitals
|
|
(AOs) using a coefficient matrix $C$, which determines how the AOs are
|
|
combined to form the MOs.
|
|
|
|
The equation for the MOs $\phi_i(\mathbf{r})$ is given by:
|
|
|
|
$$\phi_i(\mathbf{r}) = \sum_{\mu} C_{\mu i} \chi_{\mu}(\mathbf{r})$$
|
|
|
|
where $i$ labels the MO, $\mu$ labels the AO, $C_{\mu i}$ is the
|
|
coefficient of AO $\mu$ in MO $i$, and $\chi_{\mu}(\mathbf{r})$ is the
|
|
AO itself.
|
|
|
|
In some cases, it may be desirable to only compute a subset of the
|
|
MOs, for example to exclude virtual MOs that do not contribute
|
|
to the wave function. This can be achieved by selecting a subset of
|
|
columns from the coefficient matrix $C$.
|
|
|
|
The exact wave function must have a cusp at the positions of the
|
|
nuclei to ensure that the kinetic energy diverges and cancels out the
|
|
divergence of the potential, resulting in a finite total energy.
|
|
To ensure that the cusp condition is satisfied, a modification can be
|
|
made to the molecular orbitals (MOs) when the electron-nucleus
|
|
distance is smaller than a certain radius $r_{\text{cusp}}$. At
|
|
distances smaller than $r_{\text{cusp}}$, the MOs are replaced by
|
|
functions that have the correct electron-nucleus cusp condition and
|
|
that ensure that the values and the gradients of the MOs are
|
|
continuous at $r_{\text{cusp}}$.
|
|
|
|
A radius $r_{\text{cusp}\, A}$ is given for each nucleus $A$, default is
|
|
zero. If an electron is closer to the nucleus $A$ than
|
|
$r_{\text{cusp}\, A}$, the MOs are locally replaced as
|
|
\[
|
|
\phi_{\text{cusp}\, i}(\mathbf{r}) = \phi_i(\mathbf{r}) - \phi_{s_A i}(\mathbf{r}) + \sum_{k=0}^{3} f_k\, |\mathbf{r}-\mathbf{R}_A|^k
|
|
\]
|
|
where $\phi_{s_A i}$ are the contributions of the $s$ AOs centered at
|
|
$A$ to MO $i$.
|
|
The coefficients $f_k$ are such that the value and gradient of the
|
|
MO are continuous at $r_{\text{cusp}}$, and the electron-nucleus
|
|
cusp is exact.

** Update
|
|
|
|
It may be desirable to remove certain molecular orbitals (MOs) that
|
|
do not significantly contribute to the wave function. In
|
|
particular, in a single determinant calculation, the virtual MOs
|
|
can be removed as they do not participate in the ground state
|
|
configuration.
|
|
|
|
To select a subset of MOs that will be kept, an array of integers of
|
|
size ~mo_num~ can be created. If the integer corresponding to an MO is
|
|
zero, that MO is dropped and will not be included in the
|
|
calculation. If the integer is non-zero, the MO will be kept.

** Rescaling of MO coefficients
|
|
|
|
When evaluating Slater determinants, the value of the determinants
|
|
may get out of the range of double precision. A simple fix is to
|
|
rescale the MO coefficients to put back the determinants in the
|
|
correct range.
