The self-consistent field method was introduced in many-electron quantum mechanics by D. R. Hartree in Proc. Camb. Phil Soc. 24, 105 (1928), and his ideas spawned an intensive development, particularly by J. C. Slater and V. Fock.

To understand more complex atoms containing many electrons, we must solve the many-electron Schrodinger equation. Even in classical mechanics, many-body problems are difficult, so it is not surprising that many-electron quantum mechanics, usually called quantum chemistry,...

The study of matter at a molecular and sub-molecular level requires a quantum mechanical framework. In this chapter, we provide an overview of the essential concepts and notation of quantum theory needed to understand the development of relativistic many-electron quantum mechanics. This introductory overview starts from basic axioms with a focus on the nonrelativistic theory. Gauge and Lorentz invariance properties as introduced in the classical theory are then discussed for the basic quantum mechanical equations in the following two chapters.

Fortunately, the rigorous measurement theory of many-electron quantum mechanics justifies essential retention of orhital-type conceptions and their applications in bonding theory. As originally formulated by J. von Neumann in his Mathematical Foundations of Quantum Mechanics (Princeton University Press, Princeton, NJ, 1955), the fundamental object underlying quanta measurement of a pure-state iV-electron system is the density matrix F ...
