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.- The proposed organisers are:
— Walter Temmerman, Daresbury Laboratory (UK)
— Antoine Georges, Ecole Normale Sup´erieure (France) - Funding: The total estimated budget for the conference is 80.000 Euros (maximum). The ITP is contributing 15,000 Euros. The organisers have applied, unsuccessfully, for partial funding (40.000 Euros) by the European Community (under the programme “High Level Scientific Conferences”. The corresponding proposal is joined to this one, in which considerable more details can be found. CCP9 and a recently created RTN-network on f electrons could help support part of the remaining costs, so that we would like to apply for financial support by Ψk on the level of 20.000 Euros, if possible. We have also been allowed to apply to the EURESCO Committee for 5,000 Euro's through the good offices of Matthias Scheffler who will also make a direct contribution to the Conference.
- Other support (non-financial). The conference can be considered as part of a well-established series ”Electronic Structure of Solids and Other Systems” (which bring together, in particular, members of the Ψk network on electronic structure calculations cf: http://psi-k.dl.ac.uk). We will widely advertise the conference, in particular through the Ψk network.
- Training value: the conference will also have training value for young researchers. ICTP is, in that respect, an ideal venue for this activity. The computer lab will not be needed in principle.
- Programme of lectures. The programme will consist of approximately 19 one-hour and 7 halfhour contributions from invited speakers, within each of which 20 and 10 minutes respectively will be devoted to questions and discussions. A detailed list of proposed invited speakers is included in the joint EC proposal.
