Presentation of the team
The creation of our team results from the development of an activity
at the interface between physics and the sciences of living systems, initiated at the Physics Department of Ens by
Gérard Weisbuch and Gérard Toulouse at the beginning of the 80's.
With a physicist approach we study complex adaptive (living,
social or artificial) systems. We apply concepts and methods borrowed from:
- the statistical physics of disordered systems;
- the dynamics of non-linear systems.
Within the Statistical Physics Laboratory at ENS, these methods are largely applied to domains
belonging more directly to the physics of disordered systems and
of growth and form.
We make use of both analytical and numerical techniques. In addition,
an experimental psychology activity is being developped in parallel to
our modeling approach in cognitive sciences.
