! Diagonal hessian
|
|
|
|
! The hessian of the CI energy with respects to the orbital rotation is :
|
|
! (C-c C-x C-l)
|
|
|
|
! \begin{align*}
|
|
! H_{pq,rs} &= \dfrac{\partial^2 E(x)}{\partial x_{pq}^2} \\
|
|
! &= \mathcal{P}_{pq} \mathcal{P}_{rs} [ \frac{1}{2} \sum_u [\delta_{qr}(h_p^u \gamma_u^s + h_u^s \gamma_p^u)
|
|
! + \delta_{ps}(h_r^u \gamma_u^q + h_u^q \gamma_r^u)]
|
|
! -(h_p^s \gamma_r^q + h_r^q \gamma_p^s) \\
|
|
! &+ \frac{1}{2} \sum_{tuv} [\delta_{qr}(v_{pt}^{uv} \Gamma_{uv}^{st} + v_{uv}^{st} \Gamma_{pt}^{uv})
|
|
! + \delta_{ps}(v_{uv}^{qt} \Gamma_{rt}^{uv} + v_{rt}^{uv}\Gamma_{uv}^{qt})] \\
|
|
! &+ \sum_{uv} (v_{pr}^{uv} \Gamma_{uv}^{qs} + v_{uv}^{qs} \Gamma_{pr}^{uv})
|
|
! - \sum_{tu} (v_{pu}^{st} \Gamma_{rt}^{qu}+v_{pu}^{tr} \Gamma_{tr}^{qu}+v_{rt}^{qu}\Gamma_{pu}^{st} + v_{tr}^{qu}\Gamma_{pu}^{ts})
|
|
! \end{align*}
|
|
! With pq a permutation operator :
|
|
|
|
! \begin{align*}
|
|
! \mathcal{P}_{pq}= 1 - (p \leftrightarrow q)
|
|
! \end{align*}
|
|
! \begin{align*}
|
|
! \mathcal{P}_{pq} \mathcal{P}_{rs} &= (1 - (p \leftrightarrow q))(1 - (r \leftrightarrow s)) \\
|
|
! &= 1 - (p \leftrightarrow q) - (r \leftrightarrow s) + (p \leftrightarrow q, r \leftrightarrow s)
|
|
! \end{align*}
|
|
|
|
! Where p,q,r,s,t,u,v are general spatial orbitals
|
|
! mo_num : the number of molecular orbitals
|
|
! $$h$$ : One electron integrals
|
|
! $$\gamma$$ : One body density matrix (state average in our case)

|
|
|
|
! Here for the diagonal of the hessian it's a little more complicated
|
|
! than for the hessian. It's not just compute the diagonal terms of the
|
|
! hessian because of the permutations.
|
|
|
|
! The hessian is (p,q,r,s), so the diagonal terms are (p,q,p,q). But
|
|
! with the permutations : p <-> q, r <-> s, p <-> q and r <-> s, we have
|
|
! a diagonal term, if :
|
|
! p = r and q = s, => (p,q,p,q)
|
|
! or
|
|
! q = r and p = s, => (p,q,q,p)
|
|
|
|
! For that reason, we will use 2D temporary arrays to store the
|
|
! elements. One for the terms (p,q,p,q) and an other for the terms of
|
|
! kind (p,q,q,p). We will also use a 1D temporary array to store the
|
|
! terms of the kind (p,p,p,p) due to the kronoecker delta.
