Dynamical Mean Field Theory (DMFT) and Electronic Structure Calculation — •G. Kotliar — Department of Physics and Astronomy, Rutgers University, Piscataway, NJ 08854-8019, USA

We will discuss how a many body technique, DMFT is interfaced with band structure methods so as to obtain quantitative system specific information about correlated materials. Our talk will cover, computation of total energies, photoemission spectra, thermodynamical quantities transport properties phonon spectra, and optical conductivity. We will illustrate the method drawing examples from a simple system d electron system undergoing a density driven Mott transition (LaSrTiO₃) and from lanthanide and actinide materials.
