Density functional theory (DFT) calculations were employed to investigate the structural characteristics, electronic properties, and nonlinear optical properties of

The theorem gave birth to density functional theory (DFT) in which the 1-electron density rather than the many-electron wave function becomes the basic variable of the quantum chemistry. The 1-electron density is the probability of finding an electron at a given spatial position of the molecule.

Gross Annual Review of Physical Chemistry Progress in Time-Dependent Density-Functional Theory M.E. Casida and M. Huix-Rotllant This week will introduce the Density Functional Theory concepts. The week starts from an introduction to the many-body problem, and how things could be reformulated using the electron density. We will focus on observables, in particular those most directly related to the density.

Density functional theory (DFT) is a type of electronic structure calculation that has rapidly gained popularity. In this article, we provide a step-by-step demonstration of a DFT calculation by hand on the helium atom using Slater’s X-Alpha exchange functional on a single Gaussian-type orbital to represent the atomic wave function.
