    The density matrix was introduced by J. von Neumann in to describe statistical concepts in quantum mechanics. The main virtue of the density matrix is its analytical power in the construction of general formulas and in the proof of general theorems.5/5(1).   Reduced Density Matrices in Quantum Chemistry is from a special topics course of the author to graduate students at the Ohio State University. The focus of the book is on the structure of the density matrix as reference to the electronic structure of atoms and Edition: 1.

However, in most applications the charge density matrices are approximated by multiplying the point-proton density matrices with the electromagnetic coupling constant e.

The BSk series of Skyrme interactions [ – ] is one of the rare cases where the charge density is computed by folding the proton density with a Gaussian form factor. This is certainly the case of the reduced density matrices (a k a N-matrices or RDMs), whose promise of a great simplification of quantum-chemical approaches faded away when the prospects of formulating the auxil­ iary yet essential N-representability conditions turned quite bleak.

Non-relativistic energy density functionals (EDFs) of the Skyrme or Gogny type have been very successful in accounting for nuclear phenomenology for more than 40 years. Therefore, one may question the need to build a relativistic version of such approaches.

The density matrix is a representation of a linear operator called the density operator. The density matrix is obtained from the density operator by choice of basis in the underlying space. In practice, the terms density matrix and density operator are often used interchangeably.

The idea of trying to represent the ground state (and perhaps some of the excited states as well) of atomic, molecular, and solid state systems in terms of the diagonal part of the one-body reduced density matrix ρ(x) is an old one.

This allows nonlocal energy density functionals to be constructed within the framework of such models. The density matrix describing such a state cannot depend on the direction we choose for our axes. Another two-state quantum system that can be analyzed in the same way is the polarization state of a beam of light, the basis states being polarization in the x-direction and polarization in the y-direction, for a beam traveling parallel to the z.Holas and March (Phys Rev A51, ) gave a formally exact expression for the force - ∂V xc (r)/∂r associated with the exchange-correlation potential V xc (r) of density functional theory.

This forged a precise link between first- and second-order density matrices and V xc (r). Here models are presented in which these low-order matrices can be related to the ground-state electron density.Density functional theory (DFT) is a computational quantum mechanical modelling method used in physics, chemistry and materials science to investigate the electronic structure (principally the ground state) of many-body systems, in particular atoms, molecules, and the condensed phases.

With this theory, the properties of a many-electron system can be determined by using functionals, i.e.
