Hot News!!
* I've presented (December 2011)
my
habilitation thesis . You can download the short
version and the long version with articles.
* How to record a signals with the least number of measurement?
This is the subject of Compressed sensing theory, which has received
a lot of attention recently. With my colleagues we have
proposed a new approach
to this problem which seems very
powerful!
First reactions are really positive!
The ASPICS PAGE contains codes, and
data on our approach.
* For the other projects using statistical physics for different
problems, see my WASP (Widely
Applied Statistical Physics) page. In particular for the
community detection problem we have the MODE_NET project
.

* Disordered systems * Glasses and spin glasses * Constraint Optimization Problems (e.g. Graph Coloring and K-Satisfiability) * Inference and reconstruction problems (e.g. Compressed sensing and Tomography) * Nonequilibrium statistical physics * Numerical simulations and computations * Soft Matter physics * Quantum Phase Transitions
