Report :
 
This symposium deals with problems of modern solid-state physics which have strong correlations as a common root. It is a challenge, especially to theoretical physics, to explain the available data on competing phases in novel condensed matter systems, to find connections and interrelations and to obtain synergy effects. The workshop will bring together leading experts in many-body systems with a special emphasis on state-of-the-art numerical simulations of microscopic lattice models. The principal focus will be on the investigation of effective models and theories. The topics covered will include quantum phase transitions and critical phenomena, effective fermionic models, unconventional phases, superconductivity, Bose-Einstein condensates on optical lattices.

Participants of the AVEC summer school
 
Purpose of activity :
 
Changes in climate, biodiversity, deposition of nitrogen, phosphorus and sulphur, and land use are affecting European ecosystems and the services they provide to society. The vulnerability of these services to such changes can now be assessed through modern scientific techniques. The AVEC summer school presented the state of the art of such vulnerability assessments to the participants. In particular, the summer school focused on:
• the driving forces and processes of environmental change in Europe;
• the evaluation of ecosystem services provided to society;
• the full procedure of integrated vulnerability assessments, using multiple data sources, computer models, and a dialogue between scientists and stakeholders.
During the summer school, selected internationally known experts presented vulnerability assessment techniques and related issues.

Report :

The EU Concerted Action AVEC connects various European scenario-orientated assessment projects by creating opportunities for intensive exchange. An important goal of AVEC is to foster a growing European network of research on the issue of ecosystem vulnerability. The summer school is a major milestone towards achieving this goal.
The International Summer School was a two-week course where 24 selected internationally known experts presented vulnerability assessment techniques and related issues. There were two talks in the morning and one aperitif talk late in the afternoon. All presentations gave ample opportunities for long discussions. As the speakers usually stayed for some days in Peyresq these discussions could be carried on till late in the night.
At the beginning of the summer school the students presented a poster on their own research which helped all the participants to get acquainted with each other at the same time. They could select a European region, e.g. Sweden, Spain or the Alps, and one of two different scales which were offered for study; thus six working groups were formed. They came together in the afternoons and were guided by a tutor. They discussed implications of their findings for actual ecosystems in these regions and their services and compiled these in a written report. The results were presented on the last day in the plenary, the reports were revised by the working group members after the summer school and a final version was submitted.
An excursion to illustrate local ecosystems and their changes was organized to the Plateau de Valensole, Lac de Ste Croix, Les Salles sur Verdon and the Canyon du Verdon. Here the land-use change to commercial lavender growing was exemplified on the spot. At present big oak tree plantations are planted on the Plateau de Valensole which will be the basis for truffles in 10-15 years´ time. Land abandonment was demonstrated at small farms situated on the mountain sides of the Gorges du Verdon.
There was one free day which the participants could use either by staying in Peyresq and relaxing or going into the mountains near Peyresq or at the Lac d´Allos for which trip the participants had organized a bus ride themselves.
