WebJul 22, 2024 · The Fock operator is a one-electron operator and solving a Hartree-Fock equation gives the energy and Hartree-Fock orbital for one electron. For a system with 2N electrons, the variable i will range from 1 to N; i.e there will be one equation for each orbital. The reason for this is that only the spatial wavefunctions are used in Equation 9.7.1. WebWhat is its Fock space representation? I.e.

Webthe second-quantized representation for many-body post Hatree-Fock (HF) theories. In the LCAO-MO represen-tation, each molecular orbital is represented as a linear combination of a set of atomic orbitals. The expansion coeﬃcients of the MOs in terms of the AOs are obtained by solving the pseudo-eigenvalue Fock equation using the SCF procedure. In quantum mechanics, a Fock state or number state is a quantum state that is an element of a Fock space with a well-defined number of particles (or quanta). These states are named after the Soviet physicist Vladimir Fock. Fock states play an important role in the second quantization formulation of quantum mechanics.
