Brillouin Scattering, Volume 109 in the Semiconductors and Semimetal series, marks the centenary of Leon Brillouin’s seminal 1922 paper which … In quantum chemistry, Brillouin's theorem, proposed by the French physicist Léon Brillouin in 1934, relates to Hartree–Fock wavefunctions. Hartree–Fock, or the self-consistent field method, is a non-relativistic method of generating approximate wavefunctions for a many-bodied quantum system, based on the … See more The electronic Hamiltonian of the system can be divided into two parts.
