A primer in density functional theory : [lectures presented at the second Coimbra School on Computational Physics, which took place in late August of 2001

density Functional Theory (dft) Is By Now A Well-established Method For Tackling The Quantum Mechanics Of Many-body Systems. Originally Applied To Compute Properties Of Atoms And Simple Molecules, Dft Has Quickly Become A Work Horse For More Complex Applications In The Chemical And Materials Sciences. The Present Set Of Lectures, Spanning The Whole Range From Basic Principles To Relativistic And Time-dependent Extensions Of The Theory, Is The Ideal Introduction For Graduate Students Or Nonspecialist Researchers Wishing To Familiarize Themselves With Both The Basic And Most Advanced Techniques In This Field. Density Functionals for Non-relativistic Coulomb Systems in the New Century....Pages 1-55 Orbital-Dependent Functionals for the Exchange-Correlation Energy: A Third Generation of Density Functionals....Pages 56-122 Relativistic Density Functional Theory....Pages 123-143 Time-Dependent Density Functional Theory....Pages 144-184 Density Functional Theories and Self-energy Approaches....Pages 185-217 A Tutorial on Density Functional Theory....Pages 218-256 The material world of everyday experience, as studied by chemistry and condensed-matter physics, is built up from electrons and a few (or at most a few hundred) kinds of nuclei .
