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. Finally we will discuss the Hohenberg-Kohn theorems.

4. DENSITY FUNCTIONAL THEORY. Density functional theory is derived from first principle method which uses electron density as main variable to solve n-electron problem [4]–[7]. In this method the 3n-dimensional equation (problem) is transferred to n separate 3-dimensional one. This theory suggests that, there is no individual electron.

It will be the next in a series of biennial meetings, which have taken place in Paris (1995), Vienna (1997), Rome (1999), Madrid (2001), Brussels (2003), Geneva (2005), Amsterdam (2007), Lyon (2009), Athens (2011), Durham (2013), and Debrecen (2015). Density-functional theory is one of the most popular and successful quantum mechanical approaches to matter. It is nowadays routinely applied for calculating, e.g. The aim of this course is to give a thorough introduction to Density Functional Theory (DFT).
