Abstract
Hartree–Fock theory in quantum mechanics is reviewed, from the proposal of the Hartree–Fock approximation right after quantum mechanics was formulated, to its applications in modern physics. This includes a description of traditional Hartree–Fock theory in quantum chemistry, its generalizations of various kinds, and its importance for predicting the presence of symmetry breaking, or the absence thereof.
