Ecole Polytechnique doctoral dissertation prize attributed to Wahb Ettoumi, a former LPP PhD student

This prize rewards a thesis work mixing statistical physics of the long-range systems, non-linear dynamics and plasma physics. Wahb Ettoumi has developed a new approach to estimate the lifetimes of quasi stationary states that are states where the dynamics appears frozen without statistical equilibrium being reached. In some mean-field systems with N particles, an intriguing scaling law of the lifetimes in N^{1.7} got its first explanation in the article : http://journals.aps.org/pre/abstract/10.1103/PhysRevE.87.030102

The second part of his dissertation dealt with the search of the mechanisms behind sawtooth collapses in tokamak plasmas, which are a laboratory manifestation of magnetic reconnection.

Presently Wahb is working as a theoretician postdoc in the Group of Applied Physics) (GAP) at the University of Genova (Switsserland).
