  • About the Edition

    Quantal density functional theory (Q-DFT) is a new local effective potential energy theory of the electronic structure of matter. It is a description in terms of classical fields that pervade all space, and their quantal sources. The fields, which are explicitly defined, are separately representative of the many-body electron correlations present in such a description, namely, those due to the Pauli exclusion principle, Coulomb repulsion, correlation-kinetic, and correlation-current-density effects. The book further describes Schrödinger theory from the new perspective of fields and quantal sources. It also explains the physics underlying the functionals and functional derivatives of traditional DFT.

    Density functional theory (DFT) is a computational quantum mechanical modelling method used in physics, chemistry and materials science to investigate the electronic structure (or nuclear structure) (principally the ground state) of many-body systems, in particular atoms, molecules, and the condensed this theory, the properties of a many-electron system can be determined by using.

In Quantal Density Functional Theory, Sahni develops a new approach which gives insight into quantum mechanics and renders the many-fermion problem in as close to a classical mechanical and electrodynamical form as can be imagined. The book also describes Schroedinger theory from the new perspective of fields and quantal sources, and it further.
