Electronic Structure Calculations using Dynamical Mean Field Theory
Author: K. Held  Language:
The calculation of electronic properties of materials is an important task of solid state theory, albeit particularly difficult if electronic correlations are strong, for example in transition metals, . . . . .
Dynamical screening in correlated electron systems - from lattice models to realistic materials
Author: Philipp Werner, Michele Casula  Language:
Recent progress in treating the dynamically screened nature of the Coulomb interaction in strongly correlated lattice models and materials is reviewed with a focus on computational schemes based on th . . . . .
Strongly Correlated Electron Materials: Dynamical Mean-Field Theory and Electronic Structure
Author: Antoine Georges  Language:
These are introductory lectures to some aspects of the physics of strongly correlated electron systems. I first explain the main reasons for strong correlations in several classes of materials. The ba . . . . .
Dynamical Mean-Field Theory of Electronic Correlations in Models and Materials
Author: Dieter Vollhardt  Language:
The concept of electronic correlations plays an important role in modern condensed matter physics. It refers to interaction effects which cannot be explained within a static mean-field picture as prov . . . . .
Electronic Structure Calculation by First Principles for Strongly Correlated Electron Systems
Author: Masatoshi Imada, Takashi Miyake  Language:
Recent trends of ab initio studies and progress in methodologies for electronic structure calculations of strongly correlated electron systems are discussed. The interest for developing efficient meth . . . . .
Dynamical Screening Effects in Correlated Electron Materials -- A Progress Report on Combined Many-Body Perturbation and DMFT
Author: Silke Biermann  Language:
We give a summary of recent progress in the field of electronic structure calculations for materials with strong electronic Coulomb correlations. The discussion focuses on developments beyond the by n . . . . .

Dynamical Mean-Field Theory
Author: Ralf Bulla  Language:
Since the first investigation of the Hubbard model in the limit of infinite dimensions by Metzner and Vollhardt, dynamical mean-field theory (DMFT) has become a very powerful tool for the investigatio . . . . .
Dynamical vertex approximation -- an introduction
Author: K. Held, A. A. Katanin, A. Toschi  Language:
We give an elementary introduction to a recent diagrammatic extension of dynamical mean field theory (DMFT) coined dynamical vertex approximation (D$\Gamma$A). This approach contains the importan . . . . .
