SUMMARY
The Hartree-Fock approximation fails when the system cannot be accurately described by a single Slater determinant, particularly in scenarios involving non-adiabatic processes or when considering the hard repulsive core of the nuclear force at short distances. In such cases, wave functions may require linear combinations of multiple Slater determinants to capture the interactions accurately. This indicates a breakdown of the mean field approximation, necessitating more complex models to describe the system's behavior.
