Ab initio many-body for correlated electron systems

Trieste August 25-29, 2003

1 Brief scientific outline of the proposed activity
The proposed activity is motivated by recent exciting developments at the interface between two fields: that of ab-initio (density-functional based) calculations of the electronic structure of solids, and that of many-body techniques designed to handle the effects of strong electronic correlations. It is hardly necessary to emphasize the broad range of physical phenomena and potential applications of strongly correlated materials (containing incomplete d- or f-shells), such as: transition metals and their oxides as well as rare earth and actinide compounds. In those systems, many physical effects compete in a quantitative manner, so that simple models provide only general guidelines, which must be supplemented by more quantitative techniques. Recently, DFT-LDA methods have been combined with many-body techniques (in particular Dynamical Mean-Field Theory - DMFT) in order to achieve these goals.
This line of research has been the subject of recent schools, but it is now time to summarize the significant progress achieved in the field in the form of a conference which would bring together experts in the fields, as well as potentially interested researchers from both communities. DMFT would be a central theme of the conference, but by no means the only one: we would like to bring researchers using alternative approaches (such as the GW method), as well as a limited number of experimentalists and material scientists.

2 Format of the conference and funding

The proposed conference would last for 5 days, and bring together of the order of 100 scientists, including about 25 invited lecturers.
