Workshop on Recent Developments in Dynamical Mean Field Theory

Date

28–30 September 2009

Description

Materials with strong electronic correlations exhibit some of the most remarkable properties found in condensed matter systems, such as high temperature superconductivity or colossal magnetoresistance. Due to advances in materials synthesis discoveries of materials displaying novel electronic properties are reported at a growing pace, the most recent example being Fe-based "high temperature" superconductors. The theoretical understanding of the complex properties of these materials is incomplete. Deriving the proper low-energy models is far from trivial and the numerical simulation of these models poses great challenges. Hence, the properties of even the simplest models, such as the Hubbard model, are not yet fully understood.

In order to make progress, approximate descriptions of fermionic lattice models must be considered. One such approximate description, which combines computational tools and analytical considerations, is dynamical mean field theory (DMFT). DMFT calculations have provided important insights into the nature of the correlation driven metal-insulator (Mott) transition and the method has become one of the most promising tools for the study of correlated materials. The DMFT community has been energized in recent years by the development of new simulation methods which enable the study of more complex models and, therefore, promise new insights into the mechanisms underlying the remarkable phenomena observed in transition metal and actinide compounds.

The purpose of this workshop is to bring together some of the leading researchers in the DMFT community to discuss recent developments, share their latest insights and stimulate new collaborations. The workshop will also provide a platform for emerging fields such as DMFT calculations for bosonic systems or non-equilibrium DMFT.
