Shape optimization and spectral theory
Webb18 mars 2024 · The optimization procedure needs only the coordinates, the gradient and the hessian and nothing else. It has nothing to do with electrons. The SCF part is where the energy, gradient (and hessian) is calculated keeping the coordinates fixed. The SCF equations (e.g. Hartree-Fock) will involve the electrons.

We present general optimization approaches for solving variational problems involving the basis defined by the Hamiltonian using perturbation theory for its eigenvectors. The suggested operator is shown to produce better functional spaces to operate with, as demonstrated on different shape analysis tasks.
