WebThe Hartree-Fock Equations. Again, the Hartree-Fock method seeks to approximately solve the electronic Schrödinger equation, and it assumes that the wavefunction can be approximated by a single Slater determinant made up of one spin orbital per electron. Since the energy expression is symmetric, the variational theorem holds, and so we know ...

Hartree–Fock method - Wikipedia
Webt. e. In computational physics and chemistry, the Hartree–Fock ( HF) method is a method of approximation for the determination of the wave function and the energy of a quantum many-body system in a stationary state . The Hartree–Fock method often assumes that the exact N -body wave function of the system can be approximated by a single ... Web道格拉斯·哈特里(Douglas Hartree)、和弗拉迪米尔·福克(Vald-imir Foch)共同提出的哈特里-福克理论通过平均电子间的排斥并给出可接受的近似解(常常是优美的精确解)来简 … The origin of the Hartree–Fock method dates back to the end of the 1920s, soon after the discovery of the Schrödinger equation in 1926. Douglas Hartree's methods were guided by some earlier, semi-empirical methods of the early 1920s (by E. Fues, R. B. Lindsay, and himself) set in the old quantum theory of Bohr. In the Bohr model of the atom, the energy of a state with principal quantum number n is given in a… clerk of courts polk
