A local density functional theory of the ground electronic states of atoms and molecules is generated from three assumptions: i The energy functional is local.

Density functional theory of atoms and molecules

Density functional theory and Bader's atoms-in-molecules theory share the same primary ingredient: the electron density, which is the fundamental physical observable in quantum chemistry. Besides, another bridge between these two theories is built through a general formalism able to generate new local descriptors from any second-order density gradient expansion. These approaches are then applied to two classes of intramolecular bonds: between two electronegative atoms and intramolecular hydrogen bonds, illustrating how fruitful a dialog between both theories can be.

Local density functional theory of atoms and molecules.

This book is a rigorous, unified account of the fundamental principles of the density-functional theory of the electronic structure of matter and its applications to atoms and molecules. Containing a detailed discussion of the chemical potential and its derivatives, it provides an understanding of the concepts of electronegativity, hardness and softness, and chemical reactivity. Both the Hohenberg-Kohn-Sham and the Levy-Lieb derivations of the basic theorems are presented, and extensive references to the literature are included. Two introductory chapters and several appendices provide all the Two introductory chapters and several appendices provide all the background material necessary beyond a knowledge of elementary quantum theory. The book is intended for physicists, chemists, and advanced students in chemistry.

In the world you know, Eisenhower is President, Elvis is king, both televisions and countermeasures use vacuum tubes, the transistor is still experimental, a computer is a huge mainframe unit which takes up a room, the B is just entering service, airliners use propellers, the launch of the first satellite is still in the future, a manned flight to the Moon is the definition of the impossible, books are written on a typewriter and calculations are done with a slide rule. These computers will fit on a desktop, while others are small enough to sit in your lap. All these computers are vastly more powerful than any existing s mainframe computer. Many are bought by parents for their children to do homework. Yet the technical, political, and social trends that would create the PC were already developing. Gets in the way of doing the job.

 Да, да, - сказал он, - читайте эту благословенную надпись. Сьюзан стояла рядом, у нее подгибались колени и пылали щеки. Все в комнате оставили свои занятия и смотрели на огромный экран и на Дэвида Беккера.

 - Она едва заметно подмигнула.  - В этом все и. - Мидж… - Доброй ночи, Чед.

Гигантский компьютер содрогался мелкой дрожью, из густого клубящегося тумана падали капли воды. Сигналы тревоги гремели подобно грому.

Повисла долгая тишина. Сьюзан словно во сне подошла и села с ним. - Сьюзан, - начал он, - я не был с тобой вполне откровенен. ГЛАВА 73 У Дэвида Беккера было такое ощущение, будто его лицо обдали скипидаром и подожгли. Он катался по полу и сквозь мутную пелену в глазах видел девушку, бегущую к вращающейся двери.

Фонтейн пребывал в изумлении. - Неужели так. - Утечка информации! - кричал кто-то.

 Колдун, - пробурчал он себе под нос.

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 phases.
